Objectives: Neuroleptic malignant syndrome (NMS) is a life-threatening condition that occurs as an adverse reaction to antipsychotic and antiemetic agents or sudden withdrawal of dopaminergic medications. Given the metabolic and functional reserves and the comorbidities in older adults, NMS may show an atypical course., Methods: The medical records of patients with neurodegenerative diseases leading to dementia between 2013 and 2020 were reviewed for the diagnosis of NMS. Demographic and clinical characteristics of the patients were obtained from the records of laboratory parameters, management, and length of stay., Results: Fifteen older adults (19 episodes) diagnosed with NMS were included. The median age was 76 years, and 5 were female. Ten of 15 NMS patients were atypical. Most of them had an infection accompanying NMS. Neuroleptic malignant syndrome was caused by antidopaminergic agents (5 antipsychotics, 1 metoclopramide) in 6 episodes and discontinuation of a dopaminergic agent, l -DOPA, in 12 episodes. In 1 patient, it was associated with simultaneous use of domperidone and amantadine withdrawal. Rigidity in NMS due to l -DOPA discontinuation was higher than in those due to antipsychotic use ( P = 0.027). Two of our patients needed intensive care, and 1 died., Conclusions: This study highlights the high frequency of atypical NMS and the importance of early recognition of this potentially fatal syndrome, which can accompany neurodegenerative diseases and infections in older adults., Competing Interests: Conflicts of Interest and Source of Funding: The authors have no conflicts of interest to declare., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: The aging population and increasing chronic diseases make a tremendous burden on the health care system. The study evaluated the relationship between comorbidity indices and common geriatric syndromes., Methods: A total of 366 patients who were hospitalized in a university geriatric inpatient service were included in the study. Sociodemographic characteristics, laboratory findings, and comprehensive geriatric assessment(CGA) parameters were recorded. Malnutrition, urinary incontinence, frailty, polypharmacy, falls, orthostatic hypotension, depression, and cognitive performance were evaluated. Comorbidities were ranked using the Charlson Comorbidity Index(CCI), Elixhauser Comorbidity Index(ECM), Geriatric Index of Comorbidity(GIC), and Medicine Comorbidity Index(MCI). Because, the CCI is a valid and reliable tool used in different clinical settings and diseases, patients with CCI score higher than four was accepted as multimorbid. Additionally, the relationship between geriatric syndromes and comorbidity indices was assessed with regression analysis., Results: Patients' mean age was 76.2 ± 7.25 years(67.8% female). The age and sex of multimorbid patients according to the CCI were not different compared to others. The multimorbid group had a higher rate of dementia and polypharmacy among geriatric syndromes. All four indices were associated with frailty and polypharmacy(p < 0.05). CCI and ECM scores were related to dementia, polypharmacy, and frailty. Moreover, CCI was also associated with separately slow walking speed and low muscle strength. On the other hand, unlike CCI, ECM was associated with malnutrition., Conclusions: In the study comparing the four comorbidity indices, it is revealed that none of the indices is sufficient to use alone in geriatric practice. New indices should be developed considering the complexity of the geriatric cases and the limitations of the existing indices., (© 2022. The Author(s).)

Background: It is crucial to evaluate the causes of morbidity and mortality in elderly patients with dementia, such as orthostatic hypotension (OH), which may affect their daily life activities, reduce the quality of life, and increase the caregiver burden., Objective: We aimed to investigate the relationship between OH and the most common subtypes of dementia in detail., Methods: A total of 268 older adults with dementia diagnosed with Alzheimer's disease (AD), dementia with Lewy bodies (DLB), vascular dementia (VaD), and behavioral variant frontotemporal dementia (bvFTD), and 539 older adults without dementia were included in this prospective study. Comprehensive geriatric assessment including comorbidity, medication evaluation, and the head-up tilt test was also performed., Results: Of the participants, 13.8, 8.3, 6.4, and 4.8% had AD, DLB, bvFTD, and VaD, respectively. After adjusting for age, gender, the presence of comorbidities, and usage of OH-induced drugs; AD, DLB, and VaD were associated with OH (odds ratio [OR]: 2.23 confidence interval [CI] 95% 1.31-3.80; p = 0.003; OR: 3.68 CI 95% 1.98-6.83; p < 0.001, and OR: 3.56 CI 95% 1.46-8.69; p = 0.005, respectively). Furthermore, VaD was independently related to diastolic OH (OR: 4.19 CI 95% 1.66-10.57; p = 0.002), whereas AD and DLB were not., Conclusions: This study shows that elderly patients with DLB, AD, and VaD often have OH, a disabling autonomic dysfunction feature. Moreover, diastolic OH may play a role in the development of VaD. Therefore, considering potential complications of OH, it is essential to evaluate OH in the follow-up and management of those patients., (© 2021 S. Karger AG, Basel.)

Aim: The study aimed to evaluate the effect of thiazide diuretics, a first-line antihypertensive therapy, on cognitive function in elderly hypertensive patients with or without cognitive impairment., Methods: This retrospective and observational study assessed 286 elderly patients with hypertension. Patients were divided based on thiazide diuretic usage and then into dementia and non-dementia groups. The comprehensive geriatric assessment was performed for all patients. All participants were re-evaluated after a 26-week period., Results: In total, 133 patients, including 62 with dementia, took thiazide. There were no significant differences between baseline and follow-up laboratory findings, comprehensive geriatric assessment parameters, including detailed neurocognitive assessment, or electrolytes in the thiazide group, the non-thiazide group, and the dementia group (P > 0.05)., Conclusion: Thiazide therapy does not show any effect on cognitive function in older hypertensive adults regardless of dementia status., (© 2018 Japanese Psychogeriatric Society.)

Background: Geriatric syndromes are complex clinical manifestations that are not an isolated disease in older adults and have common risk factors within themselves. The syndromes are significant causes of mortality, morbidity, and increased health care costs., Objective: To determine the frequency of geriatric syndromes such as malnutrition, dementia, depression, falls, polypharmacy, urinary incontinence, pressure ulcer, sarcopenia, and frailty in community-dwelling older adults., Methods: A total of 2,816 patients, who applied to geriatric outpatient clinic and were evaluated by comprehensive geriatric assessment, were included in this cross-sectional retrospective study. Falls in the last year and urinary incontinence were recorded. Polypharmacy was accepted as concurrent use of more than four drugs. Diagnosis of dementia and depression was defined according to Diagnostic and Statistical Manual of Mental Disorders Fifth Edition diagnostic criteria. In addition, frailty and sarcopenia were evaluated according to Fried's physical frailty scale and European Working Group on Sarcopenia criteria, respectively., Results: The frequency of polypharmacy was 54.5%, urinary incontinence 47.6%, malnutrition 9.6%, depression 35.1%, dementia 21.6%, falls 33.6%, sarcopenia 31.7%, and frailty 28.3%. When all the participants were divided into three groups (60-69, 70-79, ≥80 years), all syndromes were significantly increased with age, except for depression. While 20% of cases in 60-69 years age group did not have any syndromes, 48% of cases in ≥80 years had more than four syndromes simultaneously., Conclusion: The frequency and coincidence of geriatric syndromes, except for depression, increases with age. Therefore, clinicians other than geriatricians taking care of older people should be aware of these syndromes as well as their treatment mechanisms., Competing Interests: Disclosure The authors report no conflicts of interest in this work.

Introduction/aim: Frail and cognitively impaired older patients are particularly vulnerable groups during the pandemic. Lockdowns, social isolation, and physical inactivity considerably affect physical and mental wellbeing. During the pandemic process, routine medical checks and acute medical care services may be disrupted. The study aimed to demonstrate the feasibility and effectiveness of telemedicine in the delivery of healthcare services to elderly patients during the pandemic. Materials andmethods: E-mails sent to the e-mail address of the department of geriatrics, which has been actively used for 4 years, between April 2020 and June 2021, were retrospectively evaluated. The time and reason for each application, referral to the patients, demographic data of the patients, and chronic diseases were recorded. E-mail frequencies were considered monthly time series, and time series charts for e-mail frequencies frompatients were produced. Results: A total of 374 e-mails that 213 patients sent were assessed. A vast majority, 97.6% of the e-mails, were sent by proxies. The mean age of patients was 78.7 ± 8.1 years, and 59.2% were women. Hypertension and dementia were the most common comorbidities. The applications mostly occurred in April-May and October-November 2020. The most common complaint in dementia was behavioral disturbances (13.6%). Geriatric outpatient appointments were arranged for 29.9% of the applicants, 14.2% were referred to the emergency department, and 23.0% were offered medical treatment. Outpatient examination and treatment were completed in 15% of the patients and 10.4% of them were hospitalized. The time series charts showed that e-mails were sentmore frequently by patients with dementia than the others (p = 0.03). Conclusions: Telemedicine, which enables many problems of patients to be solved in geriatric practice without face-to-face appointments, can also prevent infections and unnecessary hospitalizations, especially during these unusual pandemic days.

Aim: Alzheimer's disease (AD) and dementia with Lewy body (DLB) constitute the most common types of dementia, and are two common geriatric syndromes; however, sarcopenia has not been elaborately evaluated in DLB so far. Therefore, this study aimed to investigate the relationship between sarcopenia and DLB in older adults. Methods: In this retrospective and cross‐sectional study, 662 participants, who were followed in a memory clinic at the Geriatrics department of a university hospital, were included. Comprehensive Geriatric Assessment, including the activities of daily living, malnutrition and malnutrition risk, frailty, cognition, and sarcopenia were assessed. Sarcopenia was defined according to the revised European Working Group on Sarcopenia in Older People‐2 criteria. Results: A total of 662 participants (461 healthy controls, 133 with AD and 68 with DLB) with a mean age of 73.60 ± 7.50 years were included. The prevalence of probable sarcopenia and sarcopenia was 53.4% and 19.5%, respectively, in patients with AD, whereas it was 55.9% and 19.1%, respectively, in patients with DLB. After adjustment analyses, probable sarcopenia, sarcopenia and low muscle mass were related to AD (P < 0.001, P = 0.001, P < 0.001, respectively). Probable sarcopenia and slow gait speed were associated with DLB (P < 0.01, P < 0.001, respectively). Conclusions: Sarcopenia is common in patients with DLB and in those with AD, and seems to be closely related to low muscle strength and slow gait speed in DLB patients. Considering sarcopenia‐related negative health outcomes in older adults, the evaluation of sarcopenia, therefore, should also be among the follow‐up and treatment goals of DLB patients.

Objective: Traumatic brain injury (TBI) is nondegenerative insult to brain from external mechanical forces. It may cause cognitive impairment, psychological problems in the long period. Besides traumatic brain injury also induces neuroinflammation and neurodegeneration process, and increases risk of dementia. It may cause various psychiatric complications such as depression, posttraumatic stress disorder, generalized anxiety disorder, and other cognitive and behavioral sequela according to site of involvement in the brain. Methods: We report a patient who has behavioral symptoms, amnesia and gait apraxy after TBI. Patient's symptoms were similar to behavioral variant Frontotemporal Dementia (bv FTD). Results: After detailed neurocognitive and radiologic evaluation he was diagnosed with Normal Pressure Hydrocephalus (NPH), and Alzheimer's Disease (AD) following TBI. Conclusion: Comprehensive geriatric assessment, including detailed radiological examinations, if it is necessary, is recommended for the optimum management of elderly patients with cognitive and psychosocial problems in order to avoid misdiagnosis and inappropriate treatment.

The purpose of this study is to assess the effect of vitamin D replacement on cognitive function in older adults. A total of 560 patients who underwent comprehensive geriatric assessment including Global cognitive assessment, Basic Activities of Daily Living (BADL), and Instrumental Activities of Daily Living (IADL) twice in 6-month period were retrospectively reviewed. Oral cholecalciferol was replaced to patients with vitamin D deficiency routinely. In baseline cognitive scores, BADL-IADL scores were lower in the severe deficiency group than in the deficiency and adequate groups (P < .05). With regard to the relation between changes in cognitive functions, BADL-IADL scores on the 6-month versus baseline, no difference was determined in patients with and without dementia (P > .05). Vitamin D replacement may not improve cognitive performance in older adults, even if vitamin D is raised to adequate level, suggesting that longer term replacement therapy may be needed to improve cognitive function.
