Your brain is the control center for your entire body, controlling your movement, speech, memory and thoughts. It also regulates the functions of most of your organs, determines your abilities, what you know, remember and how you function. When it is healthy, you are able to quickly perform normal bodily and memory functions but when a disease infects your brain, it can affect nearly every part of your body. There are a wide variety of brain diseases, most of which are listed below, that affect your brain and nervous system in different ways. The causes, symptoms and treatments of these brain diseases will vary based on the condition themselves.
The first category of brain disease includes infections like Meningitis, Encephalitis and Brain abscesses. Meningitis is an inflammation of your brain’s lining and spinal cord that can cause infection. Symptoms of meningitis include headache, confusion and neck pain. Encephalitis is an inflammation of your brain tissue from infection and can occur together with Meningitis. A brain abscess is an infection in the brain caused by bacteria.
You can also get seizures from a variety of brain conditions, with the majority of them being from Epilepsy. Epilepsy has no known cause though risk factors include close relatives with the condition and a history of head injuries or stroke.
You can also get brain conditions and diseases from trauma to your head, such as a concussion which is a brain injury causing a short-lived mental disturbance, or a traumatic brain injury which is trauma causing permanent damage. You may also get a Intracerebral hemorrhage, which is bleeding inside your brain, from a traumatic brain injury.
Tumors and Masses
The brain can also get diseases from tumors and masses such as a brain tumor, Glioblastoma, Hydrocephalus which involves an increased amount of fluid in the brain, and Pseudotumor cerebri. Symptoms of tumors and masses include changes in vision, nausea, dizziness and headaches.
Blood Vessel Conditions
Many of the diseases and conditions you can get involving your brain are due to the blood vessels. These include stroke, Ischemic stroke (blood clot in an artery), Hemorrhaic stroke, transient ischemic attack, brain aneurysm, subdural hematoma, epidural hematoma, intracerebral hemorrhage, and cerebral edema.
Finally there are brain diseases stemming from neurodegenerative conditions where the brain no longer functions normally, usually from some type of nerve damage. These include Parkinson’s disease, Huntington’s disease, Pick’s disease, dementia, Amyotrophic lateral sclerosis, and Alzheimer’s disease. Most neurodegenerative conditions include the same symptoms such as a sudden lack of balance or coordination, memory loss, vision impairment, slow reaction time, confusion, headaches, dizziness, frustration, unusual mood swings, odd and different behavioral patterns, and a disruption in brain activity.
