Brain is a part of nervous system, controlling our whole body including thoughts, speech, memory and movement. If the problem occurs in brain, the results can be devastating and fatal. Brain diseases are of different forms such as infection, trauma, seizures, stroke, and tumours. Several different factors contribute in causing different forms of brain diseases. Loss of brain cells develops severe complications, which can be life-threatening.
Symptoms of brain diseases
Loss of vision
Loss of consciousness or confusion
Inability to think
Sensitivity to light
Nausea with or without vomiting
In severe cases, symptoms include numbness, incoherent speech, behavioural changes, spasms, muscle twitching and inability to wake up.
Causes of brain diseases
Seizures – This kind of brain disease is known as epilepsy. Though causes of epilepsy are not identified, but head injuries and stroke may cause epilepsy.
Infections – Meningitis, brain abscess and encephalitis are the common type of brain infections. In meningitis, there is an inflammation of lining around the brain or spinal cord due to infection. Brain abscess is an infection in brain caused due to bacteria. Encephalitis is an inflammation of the brain tissue caused due to infection.
Trauma – Concussion is a temporary disturbance in brain function caused by traumatic injuries. Intracerebral hemorrhage is an internal bleeding in brain that occurs due to hypertension or traumatic injury. Traumatic brain injury is a permanent brain damage from traumatic head injury.
Vascular conditions – Stroke results to sudden interruption in blood flow and oxygen to an area of brain. Hemorrhagic stroke causes bleeding inside in the brain, which creates congestion and pressure on brain tissue. Ischemic stroke causes blood clot suddenly in an artery, blocking blood flow and leading to stroke. Transient ischemic attack is a temporary interruption of blood flow and oxygen to a part of the brain.
Neurodegenerative conditions – Certain neurodegenerative conditions such as Parkinson’s disease, Pick’s disease, Huntington’s disease, amyotrophic lateral sclerosis (ALS), Pick’s disease, dementia, and Alzheimer’s disease causes brain disease.
Treatments for brain diseases
Treatments for brain diseases depend on the specific type of disease and its causes. Neurologist performs the test to diagnose the underlying cause of a particular disease and type of disease and accordingly recommends for the medication and surgery. Physical therapy done by the physiotherapist is also effective in treating certain type of brain diseases.
