  • Limb-girdle muscular dystrophies

  • Leukodystrophies 

  • Mental retardation

Neurology and genetic testing

Genetic testing today has become an essential part of neurological treatment. It is through these tests that we are able to comprehend the complexities of the brain, mind, and spine to a great extent. Genetic causes of a particular disorder and helps in the diagnosis and prognosis of the disorder, especially in challenging cases. 

Genetic testing for neurological disorders is essential for the following reasons

  • It gives an idea about hereditary factors responsible for a disorder.

  • Provides information about family history of any disorder.

  • It helps in accurate diagnosis of the disorder.

  • It helps in developing effective prognosis and treatment plan for the patients healing.

  • It also helps in deciding the success rate of the treatment for the disorder, as it gives a clear picture of the level of severity of the disorder.

  • It also gives an idea of the healing mechanism of the patient.

  • Provides information about what type of treatment, medicine, the patient will be sensitive or resistant to.

  • Helps in identifying neurological disorders, which can be transferred from a pregnant lady to her baby in the womb, and can further help in the prognosis and prevention n such cases.

When does a doctor advise genetic testing in neurological disorders?

A doctor may ask the patient to go for genetic testing to know facts about the heredity, family history of a particular disorder. He may ask for genetic testing to diagnose the severity of the disorder and to find out the risk level of the disorder for other family members. Genetic testing neurological disorders also help in the diagnosis and prognosis of the disorder and to estimate the success rate of the treatment and chances of relapse in the future. Sometimes it happens that there is no treatment available for a particular disorder, at that time genetic testing will help in suggesting what type of symptoms and conditions to expect and how to handle them with support and advocacy.
