Empirical support for cognitive remediation in traumatic brain injury and schizophrenia is documented by published randomized controlled trials and meta-analyses. [1] [2] [3] Effects on cognitive skill performance in schizophrenia are durable for months after the therapies are withdrawn, particularly in terms of executive functioning, working memory, and verbal memory.
[1] Someone that has post-schizophrenic depression experiences both symptoms of depression and can also continue showing mild symptoms of schizophrenia.

Schizophrenia is a mental disorder [17] [7] characterized variously by hallucinations (typically, hearing voices), delusions, disorganized thinking and behavior, [10] and flat or inappropriate affect. [7]
Recent studies have used fMRI to explore specific brain networks, such as the salience network and default mode network, to understand their roles in schizophrenia-related symptoms. Alterations in these networks may affect self-referential thoughts and responses to external stimuli, potentially contributing to symptoms like hallucinations and ...
Various brain stimulation techniques have been used to treat the positive symptoms of schizophrenia, in particular auditory verbal hallucinations (AVHs), and investigations are ongoing. [168] Most studies focus on transcranial direct-current stimulation (tDCM), and repetitive transcranial magnetic stimulation (rTMS). [169]
'This will turn out to be the most important break in the disease,' the Broad Institute's director Eric Lander said.
These rapid evolutionary changes, in some cases, may impede normal development within the social brain. [14] [15] As schizophrenia is foremost a disorder of the consciousness, it has been suggested that schizophrenia exists as an unwanted byproduct of the evolution of the prefrontal cortex and other brain regions constituting the social brain. [13]
Visual processing abnormalities in schizophrenia are commonly found, and contribute to poor social function. [ 1 ] There is evidence that schizophrenia affects perception of contrast and motion , control of eye movements , detection of visual contours, and recognition of faces or facial expressions .
