• A cross-sectional, prospective ocular motor study in 72 patients with Niemann-Pick disease type C
  June 7, 2021 by Tatiana Bremova-Ertl
  CONCLUSIONS: This is the largest cohort of NPC patients investigated for ocular-motor function. Vertical supranuclear saccade palsy is the hallmark of NPC. Vertical upward and downward saccades are equally impaired. Horizontal saccadic peak velocity and latency, vertical saccadic duration and amplitude, and horizontal position smooth pursuit can be used as surrogate parameters for clinical trials. Compensating strategies can contribute in establishing a diagnosis.
• Psychiatric and cognitive characteristics of older adults admitted to a Video-EEG monitoring (VEM) unit
  May 12, 2021 by Anthony Hew
  CONCLUSION: Psychiatric comorbidities are common among older adults admitted for VEM. The psychological impact of epilepsy and risk factors for PNES seen in younger patients are also applicable in the older group. The older group demonstrated more cognitive impairments than the younger group, although these were usually unrecognized by individuals. Older adults admitted to VEM will benefit from psychiatric and neuropsychological input to ensure a comprehensive care approach to evaluation and…

• Association of Structural Magnetic Resonance Imaging Measures With Psychosis Onset in Individuals at Clinical High Risk for Developing Psychosis: An ENIGMA Working Group Mega-analysis
  May 5, 2021 by ENIGMA Clinical High Risk for Psychosis Working Group
  CONCLUSIONS AND RELEVANCE: This study provides evidence for widespread subtle, lower CT measures in individuals at CHR. The pattern of CT measure differences in those in the CHR-PS+ group was similar to those reported in other large-scale investigations of psychosis. Additionally, a subset of these regions displayed abnormal age associations. Widespread disruptions in CT coupled with abnormal age associations in those at CHR may point to disruptions in postnatal brain developmental processes.
• The Three Glycotypes in the London Classification System of Sporadic Creutzfeldt-Jakob Disease Differ in Disease Duration
  April 27, 2021 by Blair Ney
  Sporadic Creutzfeldt-Jakob disease (sCJD) is the most common form of CJD and is believed to be caused by the misfolding and aggregation of endogenous prion protein. Several classification systems have been developed to correlate the molecular characteristics of these misfolded prions (PrP^(Sc)) to the heterogeneous clinical presentations of sCJD. A central component of these systems is glycotyping, which involves the interpretation of the results of western immunoblotting of the…
• Structural and functional neuroimaging changes associated with cognitive impairment and dementia in Parkinson's disease
  April 23, 2021 by Conor Owens-Walton
  This study seeks a better understanding of possible pathophysiological mechanisms associated with cognitive impairment and dementia in Parkinson's disease using structural and functional MRI. We investigated resting-state functional connectivity of important subdivisions of the caudate nucleus, putamen and thalamus, and also how the morphology of these structures are impacted in the disorder. We found cognitively unimpaired Parkinson's disease subjects (n = 33), compared to controls (n = 26),…
• Brain hypometabolic changes in 14 adolescent-adult patients with Niemann-Pick disease type C assessed by 18F-fluorodeoxyglucose positron emission tomography
  April 8, 2021 by Theodore Y Lau
  CONCLUSIONS: We found bilateral symmetric hypometabolism of the frontal lobes, thalami and parietal lobes (especially posterior cingulate gyrus) to be typical of adolescent-adult NPC. Ataxia was commonly associated with cerebellar or thalamic hypometabolism. Frontal lobe hypometabolism showed the best inverse correlation with clinical severity.
• Predictors of New-Onset Epilepsy in People With Younger-Onset Neurocognitive Disorders
  April 5, 2021 by Xinshi Wang
  Objective: People with neurocognitive disorders (NCDs) have an increased risk of epilepsy. However, most studies investigating the risk of seizures in people with NCDs are limited to those with Alzheimer's disease (AD) and vascular dementia (VD), and those who developed dementia after age 65 years. A knowledge gap exists regarding factors associated with development of epilepsy in people with younger-onset NCD, and those with non-AD and non-VD dementia subtypes. In this study, we aimed to…
• Genetic testing in dementia-A medical genetics perspective
  March 29, 2021 by Aamira J Huq
  CONCLUSIONS: Inclusion of genetic testing in the diagnostic pathway in some patients with dementia could potentially reduce the time taken to diagnose the cause of their dementia. Although a definite advantage as an addition to the diagnostic repository, genetic testing has many pros and cons which need to be carefully considered first.
• Odor Identification Testing Can Assist in the Clinical Distinction Between Psychiatric Disorders and Neurological/Neurodegenerative Disorders
  March 26, 2021 by Ioanna Pachi
  CONCLUSIONS: Patients with neuropsychiatric difficulties who score 8 or less on Sniffin' Sticks are more likely to have a neurodegenerative illness. A cut-off score of 8 is potentially a "red flag" for clinicians faced with the diagnostic question of PPD versus NND.
