Learn about the four causes of brain shrinkage

There are many causes of cerebral atrophy, the most common ones are physiological factors, psychological factors, serious factors and those caused by trauma. For this disease, we must treat the cause.

1. Physiological factors

As we age, the physiological functions of various organs in the human body gradually deteriorate, especially the cardiovascular and cerebrovascular (large and small arteries) where atherosclerosis occurs and microcirculation is obstructed, leading to insufficient blood and oxygen supply to the brain, degeneration and necrosis of brain nerve cells, and decreased function. This is followed by memory loss, insomnia, irritability, lack of energy, apathy, slow reaction, and stubbornness.

2. Psychological factors

Many elderly people have been in leadership positions their entire lives, but time takes its toll on them, and once they retire, they inevitably feel a little uncomfortable. In the past, everyone had to listen to them, but now they are asked to listen to others and they just won’t listen. This is why the disease is delayed and continues to worsen.

3. Inflammatory factors

Encephalitis and meningitis caused by various reasons are due to pathogens or toxins invading nerve cells, interfering with nerve cell metabolism; perivascular lymphocyte infiltration, vascular endothelial cell proliferation, thrombosis, blood circulation disorders; strong response of nervous tissue to pathogen antigens, demyelination of white matter, and vascular and perivascular destructive lesions, etc., which lead to localized or diffuse hydrops, softening or necrosis of brain tissue and brain atrophy.

4. Trauma causes brain atrophy

Chronic dural snow causes intracranial hypertension due to the space-occupying effect, local brain compression, obstruction of cerebral blood circulation, neuronal deformation and necrosis, and brain atrophy.
