Lewy body dementia(LBD) is an umbrella term for two similar and common subtypes of dementia:[1]dementia with Lewy bodies(DLB) andParkinson's disease dementia(PDD). [2][3][4][5]Both are characterized by changes in thinking, movement, behavior, and mood.[1] The two conditions have similar features and may have similar causes, and are believed to ...
Signs and symptoms. Frontotemporal dementia is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11][14] Men and women appear to be equally affected. [15] It is the most common early presenting dementia. [16]
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
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 ...
Autoimmune variants peripheral neuropathies or progressive inflammatory neuropathy could be in the list assuming the autoimmune model for MS, together with a rare demyelinating lesional variant of trigeminal neuralgia [ 104 ][failed verification] and some NMDAR Anti-NMDA receptor encephalitis.
Radiology, neurology. Amyloid-related imaging abnormalities (ARIA) are abnormal differences seen in magnetic resonance imaging of the brain in patients with Alzheimer's disease. ARIA is associated with anti-amyloid drugs, particularly human monoclonal antibodies such as aducanumab. [1] There are two types of ARIA: ARIA-E and ARIA-H.
Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, [1] is a form of small-vessel vascular dementia caused by damage to the white brain matter. [2] White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. [3]
