Thymus atrophy during early human development (childhood) is an example of physiologic atrophy. Skeletal muscle atrophy is a common pathologic adaptation to skeletal muscle disuse (commonly called "disuse atrophy"). Tissue and organs especially susceptible to atrophy include skeletal muscle, cardiac muscle, secondary sex organs, and the brain ...
Brain atrophy from vascular dementia: Specialty: Psychiatry, neurology Symptoms: Cognitive impairment, short-term memory loss [3] Complications: Heart disease, loss of ability to care for self and interact, pneumonia [4] Causes: Conditions that impair blood vessels in the brain and therefore interfere with oxygen delivery to the brain [3] Risk ...
Spinal cord injury [13] or traumatic brain injury [26] Synucleinopathy, a group of neurodegenerative diseases including pure autonomic failure, Parkinson's disease, dementia with Lewy bodies and multiple system atrophy [6] Surgery or injury involving the nerves [13] Toxicity (vincristine) [27]
[22] [69] This hypothesis suggests that two patients might have the same brain pathology, with one person experiencing noticeable clinical symptoms, while the other continues to function relatively normally. Studies of cognitive reserve explore the specific biological, genetic and environmental differences which make some people more resistant ...
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.
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. Brain atrophy can be classified into two ...
Degenerative disease is the result of a continuous process based on degenerative cell changes, affecting tissues or organs, which will increasingly deteriorate over time. [ 1 ] In neurodegenerative diseases , cells of the central nervous system stop working or die via neurodegeneration .
Multiple system atrophy is estimated to affect approximately 5 per 100,000 people. At autopsy, many patients diagnosed during life with Parkinson's disease are found actually to have MSA, suggesting that the actual incidence of MSA is higher than that estimate. [4]
