In brain tissue, atrophy describes a loss of neurons and the connections between them. Brain atrophy can be classified into two main categories: generalized and focal atrophy. [2] Generalized atrophy occurs across the entire brain whereas focal atrophy affects cells in a specific location. [2] If the cerebral hemispheres (the two lobes of the ...
Atrophy is the partial or complete wasting away of a part of the body. Causes of atrophy include mutations (which can destroy the gene to build up the organ), poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, excessive amount of apoptosis of cells, and disuse or lack of exercise or disease intrinsic to the tissue itself.
More specifically, the neurological diseases that can cause cerebellar degeneration include: [11] Diagram of two different nerve cells. The diagram on the left shows a nerve cell that is healthy and normally-functioning. The diagram on the right shows a nerve cell with a damaged myelin sheath, being the cause of multiple sclerosis.
Brain injuries have far-reaching and varied consequences due to the nature of the brain as the main source of bodily control. Brain-injured people commonly experience issues with memory. [15] This can be issues with either long or short-term memories depending on the location and severity of the injury.
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Image shows brain thousands of years old The deformed brain was found inside a roughly 2,600-year-old decapitated head that was excavated from a waterlogged pit in the U.K. in 2008.
Folate must be actively transported into the brain, so ATP from the mitochondria is essential. If the individual has a mitochondrial disease, the FRA could be lacking adequate energy, resulting in the deficiency of folate in the brain. [12] Other causes appear to be Kearns–Sayre syndrome [5] and autoantibodies to the folate receptor.
“Let’s face it—bed rotting or brain rotting is not a style of lazy living. It’s about escape,” psychologist Caitlin Slavens tells Yahoo Life. “The world is noisy, chaotic and often ...
