The structural brain correlates of neurological soft signs in healthy individuals.
It has yet to be established whether neurological soft signs (NSS), which include poor motor coordination, sensory perceptual difficulties and difficulties in sequencing of complex motor tasks, result from specific or diffuse brain structural abnormalities. Studying the neuroanatomical basis of NSS in healthy individuals may help to identify which brain areas are specifically associated with th...
متن کاملBrain Structural Correlates of INTELLIGENCE in ADHD Individuals
Neuroimaging evidences have shown the association of intelligence with several structural brain properties in normal individuals. However, this association for attention deficit hyperactivity disorder (ADHD) is need to be investigated. we estimated grey matter density of the brain using MRI scanning on 56 ADHD individuals comprising 30 combined (age=10.44±2.41, IQ=112.13±13.15, male, 24 right h...
متن کاملThe structural brain correlates of neurological soft signs in AESOP first-episode psychoses study.
Patients with schizophrenia and related psychoses have an excess of minor neurological abnormalities (neurological soft signs) of unclear neuropathological origin. These include poor motor coordination, sensory perceptual difficulties and difficulties in sequencing complex motor tasks. Neurological soft signs seem not to reflect primary tract or nuclear pathology. It still has to be established...
متن کاملThe clinical correlates of neurological soft signs in chronic schizophrenia.
Among 16 chronic schizophrenic in-patients, all had at least one neurological soft sign (NSS), and 6 (40%) had definite neurodysfunction. NSS and TD scores were highly intercorrelated, and NSS were significantly correlated with neuroleptic drug exposure. NSS correlated positively with both positive and negative symptoms and cognitive impairment but not with cerebral ventricular size on CT. Pati...
متن کاملNeurological Soft Signs in Individuals with Pathological Gambling
Increased neurological soft signs (NSSs) have been found in a number of neuropsychiatric syndromes, including chemical addiction. The present study examined NSSs related to perceptual-motor and visuospatial processing in a behavioral addiction viz., pathological gambling (PG). As compared to mentally healthy individuals, pathological gamblers displayed significantly poorer ability to copy two- ...
