Turkish Version of the Test Your Memory (TYM-TR) as a Screening Tool in Memory Clinics.

INTRODUCTION: This study compared the Turkish version of Test Your Memory (TYM) MMSE (Mini-Mental State Examination) and CDT (Clock Drawing Test) in patients with neurocognitive disorder. METHODS: After a thorough medical workup, patients with a diagnosis of neurocognitive disorder were enrolled. A cross-sectional design was used to compare the TYM results with those of MMSE and CDT. RESULTS: This study was conducted on 100 patients, including 46 males and 54 females, aged 52 to 86. The majority of patients were diagnosed with vascular neurocognitive disorder. The z-score of TYM-TR was significantly lower in the domains of registration, recall, visuospatial, and total score. The same results were achieved when CDT was added to MMSE. The same pattern was observed separately for those who were diagnosed with a mild or major neurocognitive disorder. CONCLUSION: Patients' cognitive deficits might be more evident when measured by the TYM-TR compared to the MMSE.

Apraxia for differentiating Alzheimer's disease from subcortical vascular dementia and mild cognitive impairment.

Although ideomotor limb apraxia is considered to be a typical sign of cortical pathologies such as Alzheimer's disease (AD), it has been also reported in subcortical neurodegenerative diseases and vascular lesions. We aimed to investigate the difference between AD, subcortical vascular dementia (SVaD) and mild cognitive impairment (MCI) patients by means of ideomotor limb apraxia frequency and severity. Ninety-six AD, 72 SVaD, and 84 MCI patients were assessed with the mini-mental status examination (MMSe), clinical dementia rating (CDR) and the apraxia screening test of TULIA (AST). Apraxia was significantly more frequent in the AD patients (32.3%) than in both of the SVaD (16.7%) and MCI (4.8%) patients. The frequency of apraxia was also significantly higher in SVaD patients than in MCI patients. AD patients had significantly lower apraxia scores than both SVaD and MCI patients. In addition, a significant difference was found between SVaD and MCI patients in terms of apraxia scores. These results suggest that the widespread belief of the association between apraxia and cortical dementias is not exactly correct. The significant difference between both of the dementia groups and the MCI patients suggests that the absence of apraxia can be an indicator for MCI diagnosis.

The first report of a patient with probable variant creutzfeldt-jakob disease in Turkey.

Variant Creutzfeldt-Jakob disease (vCJD) was first reported in the UK in 1996. Here, we report the first Turkish case of vCJD. A 47-year-old man, who has never lived outside of Turkey and had had no transfusion, was admitted to the University Hospital with speech disorder, cognitive decline and ataxia following depression, irritability, and personality change. The immunoassay of the 14-3-3 protein in the cerebrospinal fluid was negative. Brain magnetic resonance imaging revealed high-signal lesions involving the bilateral caudate and lentiform nucleus on T(2)- and diffusion-weighted imaging. The patient developed akinetic mutism 10 months after disease onset. The clinical presentation and neuroimaging findings were compatible with the vCJD cases reported since 1996 and met the World Health Organization's case definition for probable vCJD.
