Introduction: Acute ischemic stroke is one of the leading global causes of morbidity and mortality. Mechanical thrombectomy has improved the functional prognosis of this condition; however, hemorrhagic transformation is a common complication. Spectral computed tomography (CT) imaging, as a neuroimaging control test, distinguishes contrast extravasation from hemorrhagic transformation due to the differential behavior of materials at dual energy levels. This distinction is valuable in its clinical therapeutic management., Material and Methods: A single-center, observational, retrospective study was conducted in which the presence of various clinical, radiological, and therapeutic variables in patients with acute ischemic stroke treated with mechanical thrombectomy at our hospital between July 2022 and March 2023 was investigated using access to a dissociated database and medical records., Results: Out of 155 included patients, spectral cranial CT was performed in 63, and conventional cranial CT in 75. In the spectral CT group, 21 hyperdense images were detected, compared to 28 in the conventional CT group. In 42.8% of cases where hyperdensity was detected in the conventional CT group, it was not possible to distinguish between contrast extravasation and hemorrhagic transformation, in contrast to the 4.8% in the spectral CT group (p < 0.001)., Conclusions: Spectral CT provides high diagnostic confidence to the radiologist in identifying the type of detected hyperdensity, thereby offering significant therapeutic confidence to the neurologist in early resuming anticoagulation therapy.

Introduction: Epilepsy causes psychiatric disorders in 20-40% of patients impacting negatively on their quality of life. Lacosamide is a new antiepileptic as adjunctive therapy in partial seizures with or without generalization., Aim: We conducted a study to assess the impact of lacosamide as to the quality of life of epileptic patients. We used the HAD scale for anxiety and depression and QOLIE-10 scale for quality of life. We evaluated the efficacy and tolerability., Patients and Methods: We collected prospectively poorly controlled epileptic patients are and added lacosamide treatment. Baseline visit, at 3 and 6 months were performed. The questionnaires are completed and the epilepsy information has been collected., Results: 31 patients, age 45.5 ± 17.2 years, 64.5% males are included. Number of previous monthly crisis 1.6 ± 1.8. HAD anxiety scale shows a significant improvement at 3 and 6 months. HAD scale for depression reflects a significant improvement in quality parameters. QOLIE-10 shows significant improvement for the group with low quality of life after 3 and 6 months. After 6 months 61.3% of patients have a seizure reduction equal or more than 50% and 54.8% are seizure free. Dizziness is the most common side effect (22.8%). 74.2% continued treatment., Conclusions: Lacosamide may improve anxiety, depression and quality of life of epileptic patients regardless of seizure control. Response to treatment, adherence and side effects are similar to previous studies.

Introduction: Lacosamide is a new antiepileptic drug with a novel mechanism of action, as it selectively promotes the slow inactivation of voltage-dependent sodium channels without affecting fast inactivation. There are studies in the literature regarding its effectiveness in controlling neuropathic pain., Case Reports: We describe the use of intravenous lacosamide in the treatment of three patients with neuropathic pain: a woman with neuropathic pain in the first branch of the right trigeminal nerve during the acute phase of herpes zoster, a woman with central pain secondary to Dejerine-Roussy syndrome due to a malignant brain tumour, and a man with facial pain due to infiltration of the trigeminal nerve by a secondary lymphoma of the central nervous system. In the three cases, the administration of intravenous lacosamide has led to a considerable improvement in pain. The lacosamide dose has been 200 mg/day with excellent tolerability., Conclusion: Lacosamide can be an effective and well-tolerated alternative in the treatment of neuropathic pain and, moreover, its intravenous use can achieve pain control faster or be suitable when it is not tolerated orally.

Introduction: Hereditary haemorrhagic telangiectasia, or Rendu-Osler disease, is a congenital vascular disease that is associated with the presence of arteriovenous fistulas that cause paradoxical embolisms., Case Report: An 83-year-old female with clinical signs and symptoms of convulsive attacks and multiple cerebral infarctions in the acute phase. She also presented a history of multiple haemorrhages and iron deficiency anaemia with no clear aetiological causation. A thorough examination of her medical history revealed a family history of haemorrhages and a sister who had been diagnosed with Rendu-Osler disease, which suggested the possible existence of a pulmonary arteriovenous fistula as the aetiological causation of her cerebrovascular disease. Neurovascular Doppler ultrasonography with bubble contrast test was positive, and the presence of the fistula was confirmed by a computerised axial tomographic angiography scan of the lungs., Conclusions: Rendu-Osler disease is a rare cause of stroke due to the fact that it is usually associated with arteriovenous fistulas that can cause paradoxical embolisms. Neurovascular Doppler ultrasound scanning is useful for detecting these pulmonary fistulas by means of the bubble contrast test, which is a non-invasive test that can be carried out easily by neurologists themselves.

Introduction: Strokes are the leading cause of epileptic seizures in adults and account for 50% of seizures in those over the age of 65. These patients present certain specific characteristics with respect to the remaining population, which makes it necessary to look for medication that are suited to their particular case., Aim: To describe the effectiveness and safety of levetiracetam (LEV) in monotherapy in elderly patients with post-stroke epileptic seizures., Patients and Methods: A prospective evaluation was conducted of a series of cases consisting of patients over the age of 60 years who had suffered a stroke and had had at least one epileptic seizure in the late post-stroke phase (more than two weeks). Demographic data and the characteristics of the epilepsy and the stroke were collected. Patients began treatment with LEV in monotherapy, underwent check-ups at one and six months of treatment, and the effectiveness and safety of the drug were evaluated., Results: The sample consisted of 25 patients with a mean age of 75.2 +/- 7.6 years. They presented an average of 3.2 +/- 5.6 post-stroke seizures and the time elapsed since the stroke was 38.3 +/- 81.8 months. After six months' follow-up, 76% of the patients were still receiving treatment with LEV. Of the patients under treatment, 89.5% were free from seizures. Side effects that could be attributed to LEV were noted by 28% of patients, but did not compel them to stop treatment., Conclusions: LEV in monotherapy can be a safe, effective therapeutic option for elderly patients who have presented epilepsy following a stroke.

Aim: To describe the use of preadmission statins in patients with cerebrovascular accident and the possible predictive factors., Patients and Methods: Cross-sectional observational study of 795 consecutive patients with acute cerebrovascular accident. We assessed the differences among patients who were on preadmission statins (161) and those who were not (634), regarding vascular risk factors and clinical and neurosonological atherothrombotic disease markers. For univariate analysis, we used squared chi test, and for multivariate analysis, logistic regression analysis., Results: Preadmission statins were 20.3%. In high vascular risk patients defined based on National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III), this reached 28% and it might be 72%. Predictive factors for preadmission statins use were, in a positive sense, the antecedent of hypercholesterolemia diagnosis (OR = 189; 95% CI = 58-615; p < or = 0.001) and stroke (OR = 2.1; 95% CI = 1.2-3.6; p < or = 0.01), and in a negative sense, smoking (OR = 0.38; 95% CI = 0.18-0.81; p = 0.012)., Conclusions: In our population of patients with stroke, the predictive factors of preadmission statins did not adjust to the current therapeutic NCEP-ATP III recommendations; treatment with statins in high vascular risk population was way below the indications, it was 28% and it might be 72%.

Aim: To conduct a descriptive study of the welfare work carried out during one year in visits to ambulatory outpatient neurology clinics in the health district of Elche., Patients and Methods: We carried out a prospective study of data from the first visits to two outpatient neurology clinics between 1st May 2005 and 30th April 2006., Results: A total of 3229 first-time visits were attended, with a mean age of 56.8 years (SD: 21) and 62% were females. The incidence of first-time visits was 18.9 per 1000 inhabitants over the age of 14 years per year. In all, 18% missed their appointments. Results showed that 93.9% of the visits came from Primary Care, with a total mean delay of 30.6 days (16.1 days in the preferential cases and 35.8 in ordinary cases). The most frequent reasons for referral were: headaches (27.2%), cognitive disorders (15.9%), applications for visas or orthopaedic material (8.3%), impaired levels of consciousness/paroxysms with suspected epilepsy (7.3%), dizziness/instability/vertigo (6.8%) and tremor (5.9%). The most frequent diagnoses were headache (28% of the total number; 41.35% of the group less than 65 years old), cognitive impairment (12.24% of the total number; 28.9% of the group equal or more than 65 years old), cerebrovascular disease (8.7%) and epilepsy (5.1%). Patients with a non-neurological pathology accounted for 21.8% of the total number., Conclusions: In our environment, headache continues to be the leading reason behind referrals to the neurologist. One notable point is the high frequency with which patients without any kind of neurological disorder are referred; the same can be said for those referred for bureaucratic reasons (visas and prescriptions for orthopaedic materials).

Introduction: Inappropriate admissions to a hospital service generate unnecessary costs for our health care service. Most admissions to a hospital service come from the emergency department. The presence of a neurologist to attend hospital emergencies would be an important factor allowing admission criteria to be streamlined., Aims: To determine the number of avoidable admissions (AA) in a neurology service, and to define their characteristics., Patients and Methods: We conducted a prospective, descriptive study of the admissions that took place in the Neurology Service of the Hospital General Universitario de Elche (Alicante) over a period of three months. The neurologist determines whether admission is indicated or not. We collected demographic data concerning the patient, the admission diagnosis, neurological diagnosis, the reason for appropriateness and the reason for AA., Results: A total of 250 admissions were attended; 65 were considered to be AA (26%). The most frequent diagnoses in the cases of AA were non-neurological (32.3%), clinical findings (15.4%), neuropathies (10.8%) and epilepsy (10.8%). The reasons leading to AA were non-neurological and transfer to another service (30.8%), follow-up by neurology outpatient department (NOD) (29.2%), NOD study (21.5%), non-neurological and discharge (16.9%) and not specified (1.5%). The mean length of stay in the case of AA was 4.3 days., Conclusions: The number of AA in our service is higher than that found in other studies. On-duty neurologists, streamlining outpatient diagnostic testing and the design of flexible schedules for outpatient care would reduce the amount of resources that are used, while at the same time increasing the quality of the health service.

Introduction: Only a minority of patients with acute stroke are eligible for fibrinolysis, and the main reason for this is that time runs out and goes beyond the therapeutic window. The chief delay occurs prior to arrival at the hospital, but there is also a nosocomial delay, which has received far less attention., Aims: The purpose of our study was to describe the data on delays occurring before and after arrival at the hospital in a sample of patients with acute stroke, and to analyse possible associated factors, including the overload on health care services in the Emergency department, an aspect that has not previously been evaluated., Patients and Methods: Epidemiological data, times of delays before and after entering the hospital, means of transport used and the health care workload in the Emergency department of the day of admission were collected for all the stroke patients admitted to the Stroke Unit of the Hospital General Universitario de Alicante throughout the period under study., Results: From an initial sample of 460 patients, 423 were finally included in the study, with a mean delay before and after admission to hospital of 3.99 and 2.36 hours, respectively. Use of an ambulance and the haemorrhagic and transient ischemic attack subtypes were linked to a shorter delay before reaching the hospital, and arrival during the night shift was the only factor associated to a longer delay once inside the hospital., Conclusions: In our environment, there is a need to establish strategies aimed at shortening the times stroke patients take to reach the hospital and the time that elapses before they are attended.

Introduction: Dizziness is a common symptom at the outpatient clinic of family doctors. Its origin is usually multifactorial and its outcome is often benign. However, exists a tendency to relate the dizziness with a cerebrovascular disturbance. AIM. To determine if there are cerebrovascular disorders in patients with chronic dizziness using a non invasive technique., Patients and Methods: A prospective study was conducted. It included 404 patients without limit of age. The patients were evaluated in a Neurology Outpatient Clinic, to select those patients with chronic instability. A neurosonographic exam was performed to all those selected patients. This exam included colour duplex of the cervical arteries and transcranial Doppler., Results: Up to 54 % of the patients who were included in the study had a normal carotid study. For the rest of the patients, the thickness intima-media was the most prevalent finding. At the vertebrobasilar system the study of the vertebral arteries was completely normal in 81.7% followed by the presence of microangiopathy in 12.1%. The basilar system was also normal in a high figure (78%) followed by the microangiopathy (17.1%)., Conclusions: The vascular disturbances in the vertebrobasilar system are an exceptional finding in patients with chronic instability.

Introduction: Episodes of recurrent bacterial meningitis can occur in patients due to either congenital or acquired disorders. Congenital deformity of the bony labyrinth can be linked to a fistulous tract communicating it with the intracranial subarachnoid space. Mondini deformity is a frequent malformation in congenitally deaf patients., Case Report: We report the case of an adolescent with a history of being unable to hear in one ear who, from the age of 10 years, began to suffer repeated bacterial meningoencephalitis with microbiological recovery of Streptococcus pneumoniae on three occasions. The type of germ recovered in the cerebrospinal fluid (CSF) and the history of congenital deafness that was detected when the patient was 3 years old were the diagnostic clues to the possible anomaly of the inner ear with a CSF fistula. The clinically proven CSF rhinorrhea contributed to the diagnosis of an ear anomaly with a fistula. Computerised axial tomography and magnetic resonance studies of the petrous portion of the temporal bone revealed the malformation that was later found and closed during the surgical intervention on the affected ear. The clinical absence of rhinorrhea, a year's progression without new infections after operating on the patient and post-surgery imaging studies were all proof that the fistula had closed., Conclusions: Mondini dysplasia with CSF fistula must be included as a possible diagnosis when faced with a patient with recurrent bacterial meningoencephalitis. Imaging studies, especially magnetic resonance, enable the clinician to check the diagnosis and the CSF fistula can be closed with ear surgery.

Introduction: It is reckoned that headaches affect, at least once a year, around 90% of the population. The socioeconomic repercussion occasioned by this malady justifies the appearance in recent years of headache units., Aim: To conduct a descriptive epidemiological and health care study of the activity carried out in a headache-specific clinic., Patients and Methods: All the relevant points from the histories of patients who visited our surgery over a period of two years were collected prospectively and consecutively. The different types of headaches were classified according to the 1988 IHS criteria. Both the symptomatic and the preventive treatment were analysed., Results: In all, a total of 866 patients were found; 691 (79.8%) were females and the mean age was 39.8 +/- 15.9 years (range: 6-90 years); 208 (24%) had a history of migraine in the family; 399 (49.9%) were diagnosed as suffering from migraine: 256 (64.2%) had migraine without aura, 152 (19%) were diagnosed as having tension-type headache, and 218 (27.3%) presented chronic daily headache (CDH). The most frequently used symptomatic treatments were NSAI drugs (36.7%) and triptanes (28.4%). Amitriptyline (47.7%), beta-blockers (14.5%) and calcium antagonists (11.3%) were the main drugs used as preventive treatment., Discussion: After several years' operation of our Headache Unit, we thought there was a need to analyse the population seen in the visits. The fact that the majority of our patients were middle-aged females matched our expectations. Although most of the patients were diagnosed as suffering from M, we also want to highlight the high proportion of cases of CDH, above all associated with the abuse of analgesics.

Introduction: The link between cardiovascular risk factors and carotid atheromatosis has been shown to be more important in middle aged subjects than in the elderly., Aims: Our aim was to study the frequency of carotid and intracranial atheromatosis in a population over the age of 80 and to compare the presence of neurosonological anomalies depending on whether the patients have suffered a stroke or not. We also wished to compare the findings according to the sex of the patient., Patients and Methods: Patients over the age of 80 were studied at our Neurosonology laboratory using carotid and transcranial Doppler ultrasonography. The patients were analysed according to whether they had suffered an ischemic stroke or not. With regard to the carotid, a distinction was made between normal, non-significant atheromatosis and significant atheromatosis (stenosis > 50%). Intracranially, both the middle cerebral artery (normal, stenosis, microangiopathy and post-stenosis) and the basilar artery (normal, stenosis, microangiopathy and hyperdynamics) were studied., Results: We recorded data concerning 832 patients: 342 males (44.1%), mean age 83.63 +/- 3.25 years, and 527 (63.3%) with stroke. The carotid study was pathological, with a higher frequency in stroke patients (32.1% compared with 41.9%; p = 0.002). The presence of atheromatosis was significantly linked to a higher risk of suffering a stroke and more intensely to its being more severe. Carotid studies were pathological with a higher frequency among males (28.7% compared with 40%; p < 0.001). No significant differences were found intracranially in any of the parameters analysed., Conclusions: There is a high frequency of carotid atheromatosis in patients over 80 years of age. Regardless of the age, carotid atheromatosis appears even more frequently in patients who have suffered a stroke and in males, and is significantly associated to the risk of suffering a stroke. Intracranially, no differences were found.

Introduction: Dementia with Lewy bodies represents the third cause of dementia in the clinicopathological series reported to date., Case Report: A 79-year-old white female with a 3-year history of symptoms of dementia, Parkinsonism and visual hallucinations; the symptoms were difficult to control with medication and there was a family history of similar clinical pictures of dementia in the paternal grandfather, an aunt on the father's side and six siblings. A genetic study was not possible. The study thus involves a patient with relatives that may have had the pure or mixed variant of these dementias, without the DNA study for determining the e4 allele of the gene for apolipoprotein E that has been found most frequently in dementia due to Alzheimer.

Introduction: Carotid stenosis has been reported as being associated to lacunar infarcts (LI) with variable frequency, but the aetiopathogenic relation between them is still subject to some controversy., Aims: Our aim was to describe the prevalence of carotid disorders in a neurosonological study of a sample of patients with LI., Patients and Methods: We analysed the results of the neurosonological study conducted on patients with clinical-radiological criteria of LI who were admitted to our Stroke Unit during the period of study., Results: We studied 140 patients, and results were normal in only 42% of the cases. Stenosis > 50% was found in 10% of the cases and plaque without stenosis in 40.3% of the patients. In patients without plaque there was an increase in the tunica intima-media thickness in 7.2% of the cases., Conclusion: In most of the patients with LI there were anomalies in the study of the carotid performed using ultrasound scanning.

Introduction: Partial olfactory seizures are infrequent. They are related to the presence of lesions in the uncinate area of the temporal lobe. Patients describe smells during the ictal phase that are generally unpleasant. We report the cases of two patients with olfactory disorders of a paroxysmal nature caused by a parasellar meningioma., Case Reports: Case 1: a 43 year old male who presented paroxysmal episodes in which he perceived a bitter smell, with dysphoria, linked to the presence of a left side parasellar meningioma. Case 2: a 45 year old female who presented paroxysmal episodes during which she could smell formaldehyde and this was linked to the presence of a left side parasellar meningioma., Discussion: Olfactory seizures are related to structural alterations to the amygdala. The most frequent causes are associated to the presence of mesial temporal sclerosis and, above all, to tumours situated in the temporomesial structures that have diverse aetiologies.

Background: Atrial fibrillation is present in 24% of the population over 60 and it increases the risk of stroke by 2,4% 3%/year. Antithrombotic treatment is considered as the treatment of choice for cardioembolic stroke prevention in this patients. As far as we know there are not relevant data about the influence of these treatments on the type of stroke that may develop in these patients., Aim: Analyze whether there are differences in the clinical profile and functional prognosis after stroke in patients with atrial fibrillation depending on the type of treatment they were on at the time of occurrence of the event., Patients and Methods: We identified 67 patients who were admitted consecutively to our stroke unit with a stroke and atrial fibrillation over a period of 2 years. Patients were classified according to the type of antithrombotic treatment they were on. Functional prognosis was estimated by Rankin score at discharge., Results: Treated patient showed a non significant tendency to suffer less severe strokes and present a better functional situation at discharge than those who were not on prophylactic treatment. Treated patients had a significant higher prevalence of previous TIA (44,2% vs 9,1%; p= 0,0042) and HBP (81,4% vs 52%; p= 0,041) than non treated patients. Embolic strokes were more frequent in non treated patients., Conclusion: Antithrombotic treatment not only prevents strokes but may also contribute to the development of less severe strokes with a better functional prognosis in patients with AF and does not contribute to increase complications in these group of patients.

Introduction: Lamotrigine (LTG) is a new antiepileptic drug indicated in all kinds of partial and generalised clonic-tonic seizures, both in monotherapy and polytherapy. Between 20 and 30% of epileptic patients have poor control over their seizures despite adequate treatment., Aims: We report on our experience regarding the long-term efficacy and tolerability of LTG in refractory seizures., Patients and Methods: We conducted a consecutive 10-year study of patients who began LTG therapy following poor control of their seizures, in spite of being treated with two or more antiepileptic drugs in monotherapy or in combination. Both their epidemiological and clinical data were collected for study. We studied the efficacy of the treatment, differentiating between remission (absence of seizures), improvement (reduction>50% of the seizures), inefficacy (reduction<50%), exacerbation (increase in seizures) and its tolerability (side effects and dropout)., Results: In all, data was collected from 39 patients, 18 males (46.2%), mean age 30.9 +/- 13.7 years; mean follow up time: 27.6 +/- 23.4 months. 43.7% presented cryptogenic epilepsy, in 28.5% it was symptomatic and in the remaining 28.5% it was idiopathic. EEG readings and neuroimaging scans were pathological in 53.8% and 43.6%, respectively. After beginning therapy with LTG, 33% remained free of seizures, 43.6% improved, in 18.3% it was seen to be ineffective and 5.1% got worse. Dropout rate was 56.4%:23.1% due to insufficient control over the seizures, 17.9% owing to side effects and 15.4% because of non-compliance., Conclusion: Treatment with LTG offers a high degree of efficacy in the control of seizures in patients with refractory epilepsy, although it is limited by a high dropout rate.

Introduction: In Western countries, neurological disorders secondary to toxic nutritional problems usually present as isolated cases that are generally associated to identifiable causes (alcoholism, eating disorders, absorption disorders, use of medicines) that reduce the availability of basic nutrients, especially B group vitamins, but also folic acid (FA). The optic nerves and the peripheral axons are frequent target organs in this type of pathology, but leukoencephalopathy and spinal cord involvement may also appear, often in combination., Case Report: We describe the case of a 38-year-old female smoker with a heavy alcohol habit, who developed a subacute clinical pattern of, predominantly axonal, sensitive peripheral polyneuropathy, with vegetative fibre involvement. She also presented involvement of the posterior spinal cord, which gave rise to an ataxic disorder in the gait, as well as a severe bilateral retrobulbar optic neuropathy. Likewise, she presented macrocytosis (MCV: 118) due to megaloblastosis. She was also found to have a FA deficit but a normal vitamin B12 metabolism. With the help of supplementary vitamins, stopping drinking and the regularisation of her diet, the patient presented progressive clinical improvement, and was able to walk without support at 3 months and almost completely recovered her sight, which was corroborated by an improvement in the studies of both visual and somatosensorial evoked potentials., Conclusions: In our community, alcoholism is a frequent cause of nutritional deficiencies, which lead to neurological problems. FA is one of the nutrients that become deficient in alcoholics. More and more descriptions are being reported of peripheral polyneuropathy, retrobulbular optic neuropathy, myelopathy or leukoencephalopathy associated to FA deficiency, above all in patients with a history of alcoholism.

Introduction: Myasthenia gravis (MG) shows specific clinical features in children. It is essential to know this and also the use of diagnostic techniques used in infancy and childhood for correct diagnosis., Objectives: To analyze the clinical behaviour of this disorder and the use of complementary tests in the diagnosis of paediatric patients., Patients and Methods: We studied a group of 12 children diagnosed as having MG, who were admitted to the Instituto de Neurolog a y Neurocirug a de Ciudad de La Habana (Cuba) between March 1997 and June 2001. Data were obtained from the clinical histories regarding the clinical picture, anticholinesterase test, repetitive stimulation test (RST), simple fibre test (SFT), computerized axial tomography (CAT) of the mediastinum and the treatment given in each case., Results: Juvenile myasthenia gravis (JMG) presented in 91% of the patients studied. The average age of onset of JMG was 7.45 years, with no difference in presentation in the two sexes. The extrinsic muscles of the eye were most affected and the form with generalized clinical involvement predominated at the time of admission. The RST was positive in four of the nine patients in whom it was done (44%) and the SFT was positive in the six cases in which it was done. No changes were found in the mediastinum on CAT scanning. Mestinon and prednisone were the most commonly used drugs., Conclusion: In our group JMG was the most frequent form seen. Neurophysiological studies were very useful diagnostic tools.
