What are the tests for Alzheimer’s?
The so-called Alzheimer’s disease, also known as Alzheimer’s disease (AD), is a primary degenerative brain disease that occurs in old age and early age. It refers to a persistent high-grade neurological activity disorder.There are no obstacles in the state of consciousness, memory, thinking, analysis and judgment, visual space recognition, and emotions.
Its characteristic pathological changes are atrophy of the cerebral cortex, accompanied by β-amyloid (β-amyloid, β-AP) deposition, neurofibrillary tangles (NFT), a large number of memory neurons, and age spotsThe formation of (senileplaque, SP).
There are currently no treatments for specific treatment or reversal of disease progression.
It is also one of the four most common neurodegenerative diseases (the other three are Huntington’s disease, Lugar’s disease, Parkinson’s disease).
1, no significant changes in laboratory tests.
2, EEG can see non-absolute diffuse slow wave, α wave rhythm slows, the amplitude becomes lower; in severe cases, both sides can release 0 synchronously.
5c / s sharp wave.
Cerebral blood flow, the regional cerebral blood flow in the cerebral cortex reduces the rate of cerebral oxygen metabolism.
3, brain CT scan or MRI often show varying degrees of ventricular enlargement and cortical atrophy, sulcal widening.
