Objectives: This study was designed to evaluate the impact of other common self-reported comorbid disorders (hypertension, dyslipidemia, ischemic heart disease, diabetes mellitus, minor stroke, arthritis, low back pain or osteoporosis and depression) on health-related Quality of Life (HRQoL) of Parkinson's disease (PD) patients and to explore the association of their HRQoL with various sociodemographic and clinical factors., Methods: Data about age, gender, education, occupation, income, marital and residential status, social relations, disease duration, functional status, treatment and concomitant diseases were collected of 139 Greek patients (68 men and 71 women) with PD. Patients were consecutively recruited from the outpatient clinic of the first Neurology Department of Athens National University at Aeginition Hospital. Disease severity was assessed using the unified Parkinson's disease rating scale including Hoehn and Yahr and Schwab and England (S&E) scales. HRQoL was measured by the specific Parkinson's disease questionnaire (PDQ-39). A multivariate multiple regression model with normal errors was used for the statistical analysis., Results: The main determinants of HRQoL were low degree of independence measured by the S&E scale (F = 35.942, p < 0.001), social isolation (F = 20.508, p < 0.001), disease duration (F = 14.983, p < 0.001), sleep (F = 6.507, p = 0.013) and gastrointestinal disturbances (F = 4.643, p = 0.035) and the presence of depression (F = 6.022, p = 0.017)., Conclusion: Among the other chronic comorbidities only depression was associated with a poor HRQoL in PD patients. Functional dependence and social isolation contributed most to worse HRQoL. Our findings suggest that adequate social support and management of depression, sleep and gastrointestinal disturbances could reduce the distress and improve HRQoL in patients with PD.

Dementia is generally considered as rapidly progressive [rapidly progressive dementia (RPD)], in cases with overt cognitive impairment, established within months. Data about the relative frequency of underlying diseases in cases of RPD are few and extremely variable, depending on the clinical setting. We examined the relative frequency of the underlying causes of RPD, in a university tertiary referral center, in Athens. A series of consecutive patients presenting with RPD in a 3-year period was included. All patients received a comprehensive clinical, imaging, and laboratory evaluation. Of a total of 279 patients hospitalized for dementia diagnosis, 68 patients had RPD (37 males and 31 females). Mean age at onset +/-SD was 65.5+/-10.0. The most common cause of RPD was secondary dementias, accounting for 18 cases (26.5%). Alzheimer disease and frontotemporal dementia were almost equally represented, accounting for 12 (17.6%) and 11 (16.2%) cases, respectively. Vascular dementia, Creutzfeldt-Jakob disease, and various neurodegenerative diseases accounted for 9 cases each (13.2%). In a tertiary referral center, secondary dementias represented the most frequent cause of cases presenting with RPD. As a substantial number of these cases are potentially treatable, our finding reconfirms and underscores the importance of an exhaustive evaluation in any case presenting with RPD.

Objective: To investigate the frequency and causes of early-onset dementia (EOD) in consecutive patients in a highly specialized dementia referral center, focusing on unusual cases, particularly with early and/or rapid onset, in Athens, Greece., Methods: Patients referred for dementia diagnosis according to specific referral criteria during a 3 years period. We examined the distribution of patients diagnosis and differences in sex, education, dementia severity, cognitive function, and the duration of disease (from onset to referral) between the EOD (<65 y) and the late-onset dementia (LOD) groups., Results: From a total of 260 consecutive demented patients, there were 114 EOD patients or 44% of all demented patients. No significant differences were observed between the EOD and LOD groups in cognitive or behavioral measures. However, the duration from onset to consultation was significantly longer in the EOD group. Also, in the EOD group, the rates of patients with Alzheimer disease and Parkinson disease dementia were relatively low and the rate of patients with frontotemporal lobar degeneration was relatively high and the proportion of secondary dementias was high., Conclusions: We conclude that EOD patients are more likely to be seen in specialized settings. The underlying diseases are considerably different in EOD compared with LOD. Secondary causes are often found in patients with EOD. Patients with EOD had an unexpectedly longer time-to-diagnosis than patients with LOD. This argues for a need of better education about the clinical presentation of dementia in the young and middle aged.

Neurocysticercosis (NC) is the most frequent and widespread human neuroparasitosis. Glioblastoma multiforme, a not infrequent brain neoplasm in young adults, may have a similar clinical and radiologic presentation as NC. Coexistence of NC and brain tumors has been very rarely reported and puts into question a causal relationship between the 2 diseases. Here we report the case of a patient in which glioblastoma multiforme and cysticercosis appeared concomitantly, making their clinical distinction very difficult.

Introduction: Cavernous hemangiomas or cavernomas are uncommon vascular malformations of the central nervous system involving most commonly the cerebral hemispheres where they are detected in young to middle aged adults. We present an unusual case of acute monoparesis caused by an intramedullary cavernoma in a woman of advanced age., Case Report: A 67-year-old woman presented with walking difficulties with acute onset 2 months previously. On neurologic examination, there was a pure right leg monoparesis with moderate spasticity. Tendon reflexes were brisk and there was a Babinski's sign in her right lower limb. The initial diagnosis was lacunar stroke, but the brain magnetic resonance imaging revealed a right temporal cavernoma-obviously not associated with her monoparesis. The consequent spinal MRI revealed an intramedullary lesion at the T1 level, consistent with a cavernoma., Conclusion: Our patient presented with an acute monoparesis because of a spinal cavernoma, a most unusual occurrence.

The case of a 76-year-old female patient is presented with a two-year history of progressive dementia, apathy and gait impairment. Initially, Alzheimer's disease was diagnosed and she was given donepezil for one year with no significant improvement. An extensive blood and biochemical control revealed high serum calcium and parathormone levels, and normal thyroid hormones and anti-thyroid antibodies. Ultrasound of thyroid and parathyroid glands revealed an adenoma of the right parathyroid. The detailed investigation for causes of secondary hyperparathyroidism was negative. Due to the absence of clinical hyperparathyroidism she was initially treated conservatively. At referral, the neurological picture consisted of: mild signs of parkinsonism, moderate dementia (MMSE=15) and severe behavioural disturbances. Because of the continuous aggravation of the cognitive deficit, parathyroidectomy was decided although there were no clinical or laboratory signs of involvement from other organs. Three weeks after the operation the neurological picture showed dramatical improvement. Parkinsonism and behavioural disorders were remarkably reduced and the MMSE score raised to 25. In summary we report an exceptional case of primary hyperparathyroidism (PHPT) presenting as dementia and treated successfully by parathyroidectomy.

Sjogren's syndrome (SS), either primary or secondary, is rarely accompanied by CNS complications. We report the exceptional case of a patient with secondary SS, who presented orofacial dystonia as a consequence of her disease. Initial treatment with clonazepam and levetiracetam was unsuccessful. However, dystonia was dramatically improved by a treatment with corticosteroids. This case demonstrates that corticosteroids can be efficacious in the treatment of dystonia related to SS.
