Objective To investigate the cognitive functions in people at high risk for schizophrenia.Methods Two hundred and twenty-two people at high risk for schizophrenia and 331 normal controls were assessed with 14 neuropsychological tests. Results The results of some neuropsychological tests in people at high risk for schizophrenia were worse than those in the normal controls. These tests included information, arithmetic, digital symbol, block design, logical memory, visual memory, Stroop test, verbal fluency, tower of Hanoi, WCST and CPT (Plt;0.01). The time for trail making test A in was longer in the group at high risk for schizophrenia than in the control group (Plt;0.05).Conclusion People at high risk for schizophrenia have general cognitive deficits. Attention and executive function may represent the genetic endophenotype for schizophrenia.
ObjectivesTo explore the characteristics of cognitive deficits of Benign epilepsy of childhood with centrotemporal spikes (BECTS).MethodsA total of 61 BECTS patients who visited Neurology Clinic of Xuanwu Hospital Capital Medical University between September 2010 to December 2019 and 60 healthy controls were enrolled in our study. All patients and healthy controls performed a series of neuropsychological tests to assess their cognitive function in the "Multi-dimensional psychology" of Beijing Normal University, including attention; memory; arithmetic calculation; language processing; executive function; visuospatial processing; visual perception; psychomotor speed. Lastly, independent sample t-test and friedman test were performed on the scores of BECTS group and controls using SPSS 20.0 and we conducted a multi-factor comprehensive analysis of correlation between clinical criteria and cognitive dysfunction in BECTS.ResultsCompared with 60 healthy controls, the as group got an average score of 19.56±2.91 in Paired Association Learning Test (P<0.001), (23.67±9.50) in Word Discrimination Test (P=0.017), (61.45±13.14) in Object Quantity Perception Task (P=0.040), (6.54±1.47) in Digit Span Test (P<0.001), (5.79±5.90) in Vocal Perception Test (P<0.001), (35.10±2.33) in Taylor Complex Figure Test (P<0.001) and (700.34±493.053) (P=0.008) in Choice Reaction Time Test. The results of these tests are inferior to the control group and the remaining 10 tests are of no statistical significance. There were 36 children with onset of seizure before 8 years of age. Compared with the patients experienced onset of illness at a later age, the 36 patients exhibited lower scores in most of the neuropsychological tests including Visual Tracking Task, Spatial Memory Task, Simple Subtraction Task, Number Comparison Test, Language Rhyme Test, Word Discrimination Testand Visual Perception Task (P<0.05). 34 patients received monotherapy, and 27 received a combination of 2 or 3 anti-epileptic drugs. The scores of attention, memory, visual perception and reaction tests in the multi drug treatment group were lower than those in the single drug treatment group (P<0.05).ConclusionsChildren with BECTS have impairment in attention, vocal perception, visual perception, memory and psychomotor speed. The younger the age of onset, the more severe the cognitive impairments. The degree of cognitive deficitsinchildren treated with multi drugs was more serious than that of children treated with single drugs.
ObjectiveTo analyze of the extent of neuropsychological damage in post-traumatic epilepsy patients. MethodsOne hundred and thirty-five patients treated at the Department of Neurosurgery, the 904th Hospital of PLA from January 2016 to December 2018 were analyzed retrospectively, including 94 males and 41 females, with an average age of (32.94 ± 9.51) years. They were divided into 3 groups: 40 patients with post-traumatic epilepsy (epilepsy group): 53 trauma patients without post-traumatic epilepsy (trauma group) and 42 patients with health examination (control group). Neuropsychological assessment using the following scales: Mini-mental State Examination (MMSE): Montreal Cognitive Assessment-Basic (MoCA-B): Audio Verbal Memory Test (AVMT): Rey-Osterrieth Complex Figure Test (CFT): Trail Making Test (TMT): Hamilton Depression Scale (HAMD): Activity of Daily Living (ADL). ResultsThe results of one-way ANOVA showed that there was significant difference between all scales of epilepsy group, trauma group and control group (P<0.01). MMSE and MoCA-B scores: Compared with trauma group, epilepsy group decreased significantly, but there was no significant difference between groups (P>0.05); Memory and spatial structure ability: AVMT short/long delayed memory, CFT recall and copy test results showed that epilepsy group decreased more significantly than trauma group, and there was statistical significance between groups (P<0.05); Executive ability: TMT-A and TMT-B showed that epilepsy group spent longer time than trauma group, and there was significant difference between groups (P<0.01); Depressive symptoms: HAMD scale showed significant difference between epilepsy group and trauma group (P<0.01): while there was no statistical difference between trauma group and control group (P>0.05); Activity of daily living: ADL scale results showed that there was no significant difference between epilepsy group and trauma group (P>0.05). ConclusionPost-traumatic epilepsy can aggravate the cognitive impairment of patients, mainly in the decline of memory, spatial structure and executive ability, and prone to depressive symptoms. At the same time of treating epilepsy seizures, patients with post-traumatic epilepsy should be screened and assessed early in neuropsychology to improve their quality of life and return to society as soon as possible.
