What Are Brain Disorders? Symptoms, Treatment, And Prevention

The human brain is a complex system that controls our body and mind. It sends signals to command every part of the human body to complete physical actions.

However, diseases caused for many reasons can affect the organ, which leads to some devastating results. Unfortunately, these often occur way ahead of when it is discovered and diagnosed, taking them to an incurable state.

This article has an elaborated discussion on brain disorders and their other aspects.


What Are Brain Disorders?

Brain disorders, also known as neurological dysfunction, denote any disruption or abnormality in normal brain function. When the human brain gets infected or damaged, it affects the nervous system. 

Thus, a disrupted nervous system loses control over its regular functionalities like controlling the other organs, muscles, memory, etc.

Top 10 Brain Disorders: Types With Examples

Once a human brain gets affected, it causes several types of diseases. Below is a brief discussion of the categories of brain diseases:

Top 10 Brain Disorders

Inflammatory Brain Diseases

Brain diseases caused by inflammation is the most common one. However, these inflammatory diseases are challenging to recognize due to their symptoms like fever, headache, confusion, etc. Encephalitis is an inflammation caused in brain tissue, and Meningitis occurs in the spinal cord or brain lining.

Autoimmune Disorders

Autoimmune disorders occur when the body’s immune systems start dysfunctioning and attacking myelin. Myelin is the covering tissue of nerves. Therefore, its damage can create blurred vision, speech problems, and weakness in the legs and arms. Multiple sclerosis, Autoimmune encephalitis, and Hashimoto’s encephalopathy can be some examples.

Seizure Brain Diseases

Seizure brain disorders are disruption of brain activity from any illness or injury. Epilepsy is one of the most significant examples of this disorder. Other examples are mesial temporal lobe epilepsy, pediatric or genetic epilepsy, and post-concussive epilepsy.

Neurodegenerative Diseases

Such diseases can cause slow damage to the human brain and nervous system. Thus, it can cause confusion and a change in human personality. Additionally, it can affect the thought process and memories. Some neurodegenerative diseases are Alzheimer’s disease, Huntington’s disorder, ALS, or Amyotrophic Lateral Sclerosis.

Brain Tumours And Cancers

One of the most common brain diseases is tumor and cancer. Cancer is usually generated from tumors that enter into a malignant stage. Both malignant and benign tumors can cause damage to brain tissue. Metastatic, Meningiomas, Astrocytomas, and Glioblastomas are some examples.

Neurodevelopment Disorder

These brain disorders are caused due to impairment of the development of the central nervous system. It affects brain growth and communication ability. Autism or ADHD is a significant example of such a disorder. Some other examples can be cerebral palsy and hyper-reactive disorders.

Mental Health Or Psychological Disorders

These disorders are included in a separate group, which is entirely related to human behavior and psychology. Some commonly diagnosed mental illnesses are Bipolarity disorder, depression, schizophrenia, anxiety disorder, PTSD or Post-traumatic Stress Disorder, etc.

Brain Stem Disorders

The brain stem passes the motor-sensory indications between the brain and spinal cord. Its failure can cause damage to cranial nerves, which leads to impaired consciousness, Cranial Nerve Palsies, Dysautonomia, etc.

Brain Injury

Severe trauma to your brain can cause injuries and damage the nervous and brain tissues. Some brain injuries are Hematomas, Cerebral Edema, Contusions or bruising, and blood clots.

Brain Strokes

Brain strokes often cause permanent disabilities or paralysis in adults. Some notable names that are popular in the medical field are Ischemic and Hemorrhagic stroke. Strokes often lead to a blood flow disruption to the brain and diseases like movement disorders.

What Are The Causes Of Brain Disorders?

Now that you have gone through the brain disorders list and acquired enough knowledge let’s discuss the reason. The primary causes are as follows:

  • Traumatic brain injury
  • Inflammation
  • Stroke or disruptive blood flow to the brain
  • Genetics or inherence
