Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.
Subcortical dementias includes those diseases which predominantly affects the basal ganglia along with features of cognitive decline. Diseases such as progressive supranuclear palsy, Huntington's chorea and Parkinson's disease are different in many features from the other cortical dementias like Alzheimer's disease. Yet these patients present ...
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 ...
Alzheimer's disease (AD) is a chronic neurodegenerative disease that results in the loss of neurons and synapses in the cerebral cortex and certain subcortical structures, resulting in gross atrophy of the temporal lobe, parietal lobe, and parts of the frontal cortex and cingulate gyrus. [14]
Signs and symptoms tend to appear in late adulthood, typically between the ages of 45 and 65, although it can affect people younger or older than this. [1] Currently, no cure or approved symptomatic treatment for FTD exists, although some off-label drugs and behavioral methods are prescribed. [1]
A daily fibre supplement could help improve brain function in over 60-year-olds in just 12 weeks, new research suggests. The study showed that the simple and cheap addition of prebiotics – plant ...
[2] [3] While much research has focused on diseases of aging, there are few informative studies on the molecular biology of the aging brain (usually spelled ageing brain in British English) in the absence of neurodegenerative disease or the neuropsychological profile of healthy older adults.
In individuals with Alzheimer’s disease, the brain tissue progressively loses nerve cells and connections, while small deposits called plaques and tangles accumulate on the nerve tissue ...
