People living with schizophrenia (PLWS) and their first-degree relatives have a specific reduction in sleep spindles and an abnormality in their temporal coordination with slow oscillations that predict impaired memory consolidation.
This seems likely to be innaccurate to me. Claiming that all schizophrenics have this is questionable. But going on to say that all first-degree relatives have it seems particularly implausible.
Even if I inherited some combination of genes that caused sz. say I got a gene that carried the abnormality from my mom. Why on earth would my dad have it, and how can you say for certain my sister has it? And none of them have sz.
This article makes me say hmm 
. doesnt make sense to me.
Very interesting. Thanks for highlighting this.
I’m in agreement with @Bowens on this one. There are those that question the cognitive decline that supposedly occurs with age among the general population , not just those with schizophrenia.
Abstract
As adults age, their performance on many psychometric tests changes systematically, a finding that is widely taken to reveal that cognitive information-processing capacities decline across adulthood. Contrary to this, we suggest that older adults’ changing performance reflects memory search demands, which escalate as experience grows. A series of simulations show how the performance patterns observed across adulthood emerge naturally in learning models as they acquire knowledge. The simulations correctly identify greater variation in the cognitive performance of older adults, and successfully predict that older adults will show greater sensitivity to fine-grained differences in the properties of test stimuli than younger adults. Our results indicate that older adults’ performance on cognitive tests reflects the predictable consequences of learning on information-processing, and not cognitive decline. We consider the implications of this for our scientific and cultural understanding of aging.
I don’t have the academic credentials to argue with this. I imagine they’ll be doing some sleep studies.
