Using visual strategies to support verbal comprehension in an adolescent with Down syndrome
2011
International audience; It has been frequently reported that children with Down syndrome have deficits in verbal short-term memory while having relatively good performance in visual short-term memory tasks. Such verbal deficits have a detrimental effect on various high-level cognitive processes, most notably language comprehension. In this study, we report the case of an adolescent with Down syndrome whose verbal short-term memory and comprehension capacities are impaired. Noting that his visual memory remained relatively well preserved, we developed a remediation strategy based on his visual abilities to support his verbal memory deficit. This remediation led to significant improvements in…
High cognitive reserve in bipolar disorders as a moderator of neurocognitive impairment
2017
BackgroundCognitive reserve (CR) reflects the capacity of the brain to endure neuropathology, minimize clinical manifestations and successfully complete cognitive tasks. The present study aims to determine whether high CR may constitute a moderator of cognitive functioning in bipolar disorder (BD).MethodsOne hundred and two patients with BD and 32 healthy controls were enrolled. All patients met DSM-IV criteria for I or II BD and were euthymic (YMRS ≤ 6 and HDRS ≤ 8) during a 6-month period. All participants were tested with a comprehensive neuropsychological battery, and a Cerebral Reserve Score (CRS) was estimated. Subjects with a CRS below the group median were classified as having low C…
Age and sex related changes in episodic memory function in middle aged and older adults
2014
Age-related change in episodic memory function is commonly reported in older adults. When detected on neuropsychological tests, it may still be difficult to distinguish normal from pathological changes. The present study investigates age-and sex-related changes in a group of healthy middle-aged and older adults, participating in a three-wave study on cognitive aging. The California Verbal Learning test (CVLT-II) was used to assess their episodic memory function. A cross-sectional analysis of results from the first wave showed higher performance in females than males, with a steeper age-related decline in males. This was confirmed in a longitudinal analysis using a mixed effects regression m…
Cognitive Deficits and Associated ERP N400 Abnormalities in FXTAS With Parkinsonism
2018
Objective: To examine cognitive deficits and associated brain activity in fragile X-associated tremor/ataxia syndrome (FXTAS) patients with parkinsonism (FXTp+), in relation to FXTAS patients without parkinsonism (FXTp-), and normal elderly controls (NC). Methods: Retrospective reviews were performed in 65 FXTAS patients who participated in the event-related brain potential (ERP) study and also had either a videotaped neurological examination or a neurological examination for extrapyramidal signs. Parkinsonism was defined as having bradykinesia with at least one of the following: rest tremor, postural instability, hypermyotonia, or rigidity. Eleven FXTp+ patients were identified and compare…
The use of the Free Recall Method in the Analysis of Verbal Memory Deficits in Dual Diagnosis Patients
2009
In schizophrenia there are specific cognitive deficits including verbal memory deficits. The objective of this study was to examine short-term verbal memory differences between subjects with and without a dual diagnosis.A group of 80 patients with a diagnose of schizophrenia were examined. 40 of them never used illicit drugs, the other 40 also received a diagnose of addiction to psychoactive substances. The Free Recall Method was used to compare two examined groups. The results of addicted and not addicted schizophrenic patients were analyzed in all trials of the 5 stages of the examination with the use of Free Recall Method. Persons suffering from schizophrenia can usually repeat much fewe…
Verbal learning and memory and their associations with brain morphology and illness course in schizophrenia spectrum psychoses.
2012
The California Verbal Learning Test and structural brain imaging were administered to 57 subjects with schizophrenia spectrum disorders and 94 controls in a general population sample. Cases had lower semantic cluster scores. Poorer verbal memory strategies were associated with longer duration of illness and heavier use of antipsychotic medication. After controlling for duration of illness, sex, and total gray matter, poorer verbal memory was associated with lower gray matter volume in the cingulate cortex, juxtapositional lobule, right superior temporal gyrus, and precuneus. After controlling for use of antipsychotic medication, there was an association between higher serial clustering and …
Comparative study of neurocognitive function in euthymic bipolar patients and stabilized schizophrenic patients.
2009
Few studies have compared neurocognitive performance in euthymic patients with bipolar disorder (BD), stabilized patients with schizophrenia (SC) and normal controls (NC) using a comprehensive neuropsychological battery, and those that have been conducted have yielded discrepant results. We evaluated the neurocognitive profile shown by 73 euthymic patients with BD, 89 stabilized patients with SC and 67 NC. All participants completed a cognitive battery in which the domains evaluated were executive functioning, sustained attention, and verbal and visual memory. Individuals with BD were administered the Quality of Life Scale (QLS). Patients with BD manifested dysfunction in executive function…
Effects of atypical antipsychotics on neurocognition in euthymic bipolar patients.
2011
Abstract Background Different factors may influence cognitive functioning in bipolar disorder such as the effect of subsyndromal symptoms, the history of psychotic symptomatology or substance abuse, negative symptomatology, chronicity, sleep disturbances, and hormonal factors. The effect of pharmacologic treatment on cognition is still uncertain because of an insufficient number of studies examining this issue. Objective The aims of this study were to compare neuropsychologic performance of treated bipolar patients with that of controls, including unmedicated patients and healthy subjects, as well as to evaluate possible neurocognitive differences among 3 different atypical antipsychotics. …
