Angular gyrus damage refers to four symptom clusters, including finger loss, inability to calculate, inability to write, and left-right disorientation. Angular gyrus impairment is a lesion of the parietal and temporal gyrus of the main hemisphere, and occlusion of the posterior parietal artery or angular gyrus artery is common. It can also be seen in brain tumors, traumatic brain injury, brain atrophy, alcoholism, carbon monoxide poisoning, various psychiatric disorders, and hypnotic states. The appropriate diet for patients with angular gyrus damage is as follows. 1, eggs: brain activity function, memory strength and acetylcholine content in the brain is closely related. The egg yolk is rich in lecithin by the enzyme decomposition, can produce a rich acetylcholine, into the blood and will soon reach the brain tissue, so 1-2 eggs a day can supply enough choline to the body, to protect the brain, improve memory is very good. 2, milk: milk is a near-perfect nutrition in the post-traumatic brain injury diet. It is rich in protein, calcium, and amino acids necessary for the brain. The calcium in milk is most easily absorbed and is an important substance indispensable for brain metabolism. In addition, it also contains elements such as vitamin B1, which is very beneficial to nerve cells. If you have insomnia due to overuse of the brain, a glass of hot milk before going to bed can help you fall asleep.
