Most Common Neurological Disorders and Their Symptoms

Neurological disorders are the diseases and disorders related to the central and peripheral nervous systems. In simple words, it is a disorder related to the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, neuromuscular junction, and muscles. 

There are different diseases like Parkinson’s, dementia, Alzheimer’s, etc that fall under neurological disorders. Neurological disorders are extremely harmful and can affect your body and brain to a great extent leading to issues like impaired vision, loss of muscle strength, the decline in cognitive ability, etc. 

Neurological disorders affect a lot of people on a yearly basis. It is very important to know about these disorders and their symptoms in order to treat the patient and save their life.

More than 6 million people die due to stroke each year. And similarly, other neurological disorders claim a huge number of lives every year.

The following are the most common neurological disorders and their symptoms:


Headache, in simple terms, is a pain arising from the head or the upper neck of your body. It might sound like a small issue, but headaches are one of the most common neurological disorders affecting people of all ages and genders. 

You might think a headache is common and is something that happens when you are tired or stressed, but sometimes a chronic headache can be a symptom of an underlying condition. 

Headaches broadly fall into the following different categories-

  • Migraines
  • Cluster headaches
  • And tension headaches

Any minor headache occurring for a short period of time is nothing to worry about and it can be treated by resting or taking medicines. However, if the headaches occur repeatedly, it’s a sign that you should visit a neurology center and consult a doctor. 

The following are the common symptoms of chronic headache:

  • Continuous pain in the head and upper neck area
  • Pain and heaviness in the eyes while looking at bright objects 
  • Dizziness and vertigo 
  • Tenderness in the scalp area 
  • Nausea


A stroke is a neurological condition where the blood supply to the brain is disrupted or reduced due to blockage or compressed nerve, preventing the brain tissue from receiving the required amount of oxygen and nutrients. 

Stroke is another most common neurological disorder affecting millions of people every year. A stroke occurs when the arteries leading to the brain or the arteries within the brain get impaired, causing damage to the brain. 

A person suffering from a stroke needs immediate medical help as the brain cells begin to die within a minute. The worst part about a stroke is that it’s really very difficult to anticipate a stroke. 

The following are the most common symptoms of a stroke:

 Blurred vision and difficulty to see things around you

  • Not being able to balance yourself and frequently experiencing dizziness 
  • Numbness and weakness in different parts and muscles of the body
  • Severe continuous headache 
  • Trouble in walking or lack of coordination
  • Difficulty in speaking 
  • Sudden confusion and difficulty in understanding things 


Dementia is a collective term used to describe a number of issues related to the brain. Dementia is not a disease in itself, but it is a common term used to describe symptoms of decline in memory, difficulty in communicating, and thinking. 

Dementia is most common in old age people as aging leads to continuous loss of brain tissues which affects behavior, memory, perceptions, emotions, etc. 

The following are some of the common symptoms of dementia: 

  • Loss of memory and difficulty in remembering and recollecting things 
  • Difficulty in concentrating or focusing on anything like ready or writing
  • Difficulty in communicating or understanding words
  • Sudden mood swings 
  • Getting confused over small things easily

Parkinson is a nervous system disorder that affects your body movements. It is a progressive disorder that tends to worsen over the course of time. It normally affects people above the age of 55 or 60. 

Parkinson is caused when one or more nerve cells in the brain are damaged resulting in the decline of the dopamine levels in the brain. The symptoms become more evident as the dopamine levels become too low. 

The worst part about Parkinson is that it has no cure. Treatments can only help to lower the symptoms. 

The following are the common symptoms of Parkinson’s:

  • Tremor or shaking of your hands or fingers 
  • Body movements become slow
  • Stiffness and tightness in the muscles 
  • Loss of the sense of smell
