What Are Some Different Types of Brain Diseases?

Brain diseases include brain infections, such as meningitis, encephalitis and brain abscess, brain trauma, such as concussion and intracerebral hemorrhage, and stroke, states WebMD. Brain disorders can cause memory problems, lack of muscle control, convulsions and problems with vision, notes Healthline.

Brain diseases can result from the inflammation of the spinal cord, the lining around the brain, or meningitis of the brain tissues, mainly due to a viral infection, reports WebMD.

A brain abscess is a mass of pus in the brain tissue that can result from fungal or bacterial infection, surgery or trauma, according to Drugs.com. People with impaired immune systems are more likely to have this condition.

High blood pressure may cause intracerebral hemorrhage, a condition characterized by bleeding in the brain, explains WebMD. A brain injury such as concussion can cause a disturbance in brain function, resulting in unconsciousness and headache. A tumor also may develop in the brain due to an abnormal growth of tissues exerting pressure on the brain.

The formation of a blood clot in an artery may block the blood flow to the brain, causing ischemic stroke, explains WebMD. Stroke also can occur from a brain aneurysm, a condition in which a weak area develops in an artery in the brain, causing swelling and bleeding. Other brain diseases include vasculitis, or inflammation of the blood vessels, and multiple sclerosis, where the immune system attacks body nerves, causing fatigue and muscle spasm.
