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.
Altered brain structure in chemotherapy patients provides explanation for cognitive impairment. [12] Another study in 2007 investigated the differences in brain structure between two adult, monozygotic twin females. One underwent chemotherapy treatment for breast cancer, while the other did not have cancer and was not treated with chemotherapy.
The brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. [6] The brain matter can be broadly classified as either grey matter, or white matter.
For people with brain tumors, radiation can be an effective treatment because chemotherapy is often less effective due to the blood–brain barrier. [ citation needed ] Unfortunately for some patients, as time passes, people who received radiation therapy may begin experiencing deficits in their learning, memory, and spatial information ...
Brain volume continues to decrease as we age—including the frontal lobe and hippocampus, the areas responsible for cognitive functions—with the rate of shrinkage increasing by around age 60.
Radiation therapy uses high energy rays to destroy cancer cells or to shrink tumors. The kind of rays used are x-rays, gamma rays, electron beams or protons. According to the National Cancer Institute, [1] there are two types of radiation therapy: external radiation therapy; internal radiation therapy
WASHINGTON (AP) — Alzheimer’s quietly ravages the brain long before symptoms appear and now scientists have new clues about the dominolike sequence of those changes — a potential window to ...
Progressive supranuclear palsy (PSP) is a late-onset neurodegenerative disease involving the gradual deterioration and death of specific volumes of the brain. [1] [2] The condition leads to symptoms including loss of balance, slowing of movement, difficulty moving the eyes, and cognitive impairment. [1]
