Heart insufficiency has a negative impact on gray matter in the brain. Weak heart function was linked to decreased gray matter in areas of the brain associated with memory and learning, including the hippocampus and parietal medial cortex. This may increase the risk of Alzheimer's disease.
Cardiorespiratory exercise improves gray matter volume in areas of the brain associated with age-related cognitive decline. The findings add weight to the previous studies which link physical activity to neuroprotection against age-related cognitive decline.
Teens with a particular pattern of brain development have an increased frequency of drunkenness, a new study reports. Decreased gray matter density in the frontal and temporal brain regions was associated with an increased risk of teenage over-drinking.
Telomere lengthening resulted in structural changes in the brain, including cortical thickening. By contrast, telomere shortening is associated with gray matter reduction, specifically in the precuneus.
Neuroimaging reveals 'successful' psychopaths (those who can control their antisocial tendencies) have greater levels of gray matter density between the left and right ventromedial prefrontal cortex. This area of the brain is implicated in self-regulatory processes, including reactive emotions.
Neuroimaging study reveals teens with more gray matter in the caudate nucleus and left cerebellum were at increased risk of problem alcohol use over time. The findings reinforce the idea that brain structure differences may contribute to both psychiatric and substance use disorders.
A novel PET neuroimaging tracer detects abnormal inflammation in the cerebral gray matter of patients with secondary progressive multiple sclerosis.

Neuroimaging reveals Holocaust survivors have decreased gray matter in brain structures associated with emotional processing, memory, and social cognition. Early results show similar neuroanatomical changes in the children of survivors, suggesting an epigenetic link.

Neuroimaging helps researchers observe what happens in the brain as a person is rotated. The study, which gives insight into how the brain moves after the head stops moving, also provides critical information for advancing studies of TBI.

A deficiency of the SHANK3 gene, a gene associated with ASD, results in structural and functional deficits in the prefrontal cortex. The functional and structural alterations in the PFC were linked to an impairment in social interaction in male mice.
Obesity is associated with alterations in brain structure, including lower gray matter volume and smaller globus pallidus volume.
