Example of a VBM analysis on patients who experience cluster headaches.. Voxel-based morphometry is a computational approach to neuroanatomy that measures differences in local concentrations of brain tissue, through a voxel-wise comparison of multiple brain images.
Treatments with anticancer chemotherapeutic agents often are toxic to the cells of the brain, leading to memory loss and cognitive dysfunction that can persist long after the period of exposure. This condition, termed chemo brain, appears to be due to DNA damages that cause epigenetic changes in the brain that accelerate the brain aging process ...
A study showed that infusing the nourishing cerebrospinal fluid from around brain cells of young mice into aged brains rejuvenates aspects of the brain, proving that it play a role in brain aging and inter alia identifying a protein FGF17 as a key target for potential therapeutics, including for anti-aging.
Studies reveal that individuals who engage in physical activity increase the cortical volume of gray matter later in life, preventing age-related atrophy and promoting attentional control. [20] However, because most individuals' brains undergo pathological changes after the age of 80 or develop cardiac disease, neuron loss occurs and the brain ...
The amygdala, cerebellum, and many other brain regions have been implicated in autism. [15]Unlike some brain disorders which have clear molecular hallmarks that can be observed in every affected individual, such as Alzheimer's disease or Parkinson's disease, autism does not have a unifying mechanism at the molecular, cellular, or systems level.
Autism in Adulthood is a quarterly peer-reviewed academic journal covering research across a range of disciplines on all aspects of autism spectrum disorders in adults. It was established in 2019 and is published by Mary Ann Liebert. The founding editor-in-chief is Christina Nicolaidis (Portland State University). [1]
Mostly in the frontal cortex, these differences often stem from a smaller brain volume, and the decreased blood flow that results influences the hypofrontality. [9] It has not been determined if the reduction of the frontal cortex is the ultimate cause of the symptoms, or if the condition worsens as the symptoms develop.
Brain growth is usually less affected than whole body weight or length. Several studies from developed nations have found that with the exception of extreme intrauterine growth retardation also affecting brain growth, and hypoxic injury, IUGR seems to have little or no measurable effect on mental performance and behavior in adolescence or
