Genetic testing for inherited disorders helps identify genetic changes that may increase the risk of certain neurological conditions or explain symptoms that run in a family. It can be particularly useful when patients have a strong family history of neurological disease, unexplained developmental or neurological symptoms, or a condition suspected to have a hereditary cause.
Who May Benefit from Genetic Testing?
Genetic evaluation may be recommended for individuals with a family history of inherited neurological disorders, early-onset neurological conditions, unexplained seizures, developmental concerns, movement disorders, or other symptoms that suggest a possible genetic link. Your doctor may recommend a specific test based on your medical and family history.
What Does the Test Involve?
Depending on the suspected condition, testing may involve a blood or saliva sample. A genetic laboratory analyzes the sample for specific gene variants or broader genetic changes. Results should be interpreted by a qualified healthcare professional because a genetic finding does not always mean that a person will develop a particular disease.
