Background: Severe cognitive impairment affects many patients with schizophrenia, especially geriatric in-patients. Little is known about the course of this impairment, however.
Method: Two hundred and twenty-four geriatric schizophrenic in-patients were examined for changes in cognitive functioning over a one-year follow-up period, and 45 of them were assessed over a two-year period. In addition, the subset of 45 patients participated in a one-week and one-month test-retest reliability study of the instrument used to assess cognitive impairment, the Mini-Mental State Examination (MMSE).
Results: The average MMSE scores did not change over a one- or two-year follow-up period. The test-retest reliability of the scale was extremely good at both retest intervals.
Conclusion: Among the implications of these data are that cognitive changes in geriatric schizophrenic patients are very slow and are more consistent with a neurodevelopmental process than a neurodegenerative course.

Duchenne muscular dystrophy (DMD), an X-linked neuromuscular disorder, characterised by progressive immobility, chronic inflammation and premature death, is caused by the loss of the mechano-transducing signalling molecule, dystrophin. In non-contracting cells, such as neurons, dystrophin is likely to have a functional role in synaptic plasticity, anchoring post-synaptic receptors. Dystrophin-expressing hippocampal neurons are key to cognitive functions such as emotions, learning and the consolidation of memories.

Objective: To conduct a systematic review of neurocognitive dysfunctions in patients with childhood-onset schizophrenia (COS), a neuropsychiatric disorder that occurs before age 13 and is rarer and more severe than adult-onset schizophrenia.
Method: A search was made in the PubMed database. Sixty-seven studies (out of 543) which analyzed Intellectual Quotient (IQ), attentional, memory and executive functions were selected by two independent researchers.

Diabetic cognitive dysfunction is one of the important comorbidities and complications of diabetes, which is mainly manifested by loss of learning ability and memory, behavioural disorders, and may even develop into dementia. While traditional anti-diabetic medications are effective in improving cognition and memory, long-term use of these medications can be accompanied by undesirable side effects. Therefore, there is an urgent need to find safe and effective alternative therapies.
