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 ...
It is located above the brain stem, posterior to the brain. Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [1] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration, and alcoholic or nutritional cerebellar ...
Age-related decrease in gray matter volume was the largest contribution to changes in brain volume. Moreover, neuronal density appears to decrease, white matter microstructure gets altered and energy metabolism in the cerebellum gets altered. [16] General cortical atrophy occurs in aging and e.g. the caudate nucleus volume appears to decrease.
Ventriculomegaly is a brain condition that mainly occurs in the fetus when the lateral ventricles become dilated. The most common definition uses a width of the atrium of the lateral ventricle of greater than 10 mm. [ 1] This occurs in around 1% of pregnancies. [ 2] When this measurement is between 10 and 15 mm, the ventriculomegaly may be ...
Magnetic resonance imaging can observe deterioration, including progressive loss of gray matter in the brain, from mild cognitive impairment to full-blown Alzheimer disease. [19] A technique known as PiB PET imaging is used to show the sites and shapes of beta amyloid deposits in living subjects using a 11 C tracer that binds selectively to ...
Diet and lifestyle modification (e.g. low-protein diet in diabetic nephropathy, smoking cessation, weight loss, improved nutrition, and regular exercise). [16] [25] [26] Intensive management of coexisting conditions and risk factors (e.g. adequate control of blood pressure, diabetes and related metabolic abnormalities and lipid management). [25 ...
Periventricular leukomalacia ( PVL) is a form of white-matter brain injury, characterized by the necrosis (more often coagulation) of white matter near the lateral ventricles. [ 1][ 2] It can affect newborns and (less commonly) fetuses; premature infants are at the greatest risk of neonatal encephalopathy which may lead to this condition.
Cerebral edema is a potentially life-threatening complication of severely decreased sodium ion concentration in the blood (hyponatremia). [17] Ionic brain edema can also occur around the sites of brain hemorrhages, infarcts, or contusions due to a local plasma osmolality pressure gradient when compared to the high osmolality in the affected tissue.
