Prediction: There is a mechanistic relationship between mental health and sleep
How bad is sleep and circadian rhythm disruption in schizoprenia?
These results are from the study by Foster and colleagues in which the sleep-wake activity and circadian rhythms of 20 patients with schizophrenia and 21 healthy controls were compared over a period of six weeks. This image is the sleep profile of a control subject with n…

How bad is sleep and circadian rhythm disruption in schizoprenia?
Exposure to ambient light was significantly less in patients with schizophrenia than in healthy controls. This may have impaired setting of the internal clock and the circadian melatonin rhythm.

How bad is sleep and circadian rhythm disruption in schizoprenia?
This slide shows a comparison of the electroencephalogram (EEG) patterns of an unemployed control subject (top panel) and a patient with schizophrenia (lower panel). It shows fragmentation of sleep stages in the patient. There is less REM sleep and less of the stages of s…

Sleep is associated with many important and restorative processes. These include consolidation of memory, information processing, tissue repair and rebuilding of metabolic pathways, and clearance of toxins, including beta-amyloid. Sleep draws upon all of the neurotransmit…

Partial consolidation of sleep and circadian rhythm disruption using CBT reduces symptoms in schizophrenia
Sleep may represent a new therapeutic target, both in the prevention of mental illness and its treatment. There is evidence from a pilot study that cognitive behaviour therapy for insomnia can improve the condition of schizophrenic patients with persistent persecutory del…

24h rhythms have their origins within the brain. If we look at the base of the brain – where the optic nerves fuse and enter the brain. The small region above this site – deep within the brain – contains a pair of small nuclei – called the suprachiasmatic nuclei (SCN). Ea…

The cerebellum is supplied with blood via three branches of the basilar artery – the posterior inferior cerebellar artery (PICA), the anterior inferior cerebellar artery (AICA), and the superior cerebellar artery (SCA).
The image shows how the blood supply of the brain is arranged.
