Neurological Disorders affect the nervous system. Structural or functional problems in the brain, brain stem, spinal cord, and nerves, which are part of the nervous system, cause neurological disorders. There are hundreds of identified neurological disorders. Physical, behavioral, and mental symptoms may occur separately or together depending on which region of the nervous system is affected.
Neurological problems can be caused by many different reasons, such as congenital anomalies, infections, injuries, and genetic disorders.
Genetics in Neurological Disorders
It is known that many neurological diseases have a genetic basis. Many diseases such as epilepsy, autism spectrum disorders, learning difficulties, hearing loss, and movement disorders are included in this group. Most neurogenetic diseases occur early in development and can be diagnosed early. However, there are also neurological diseases that occur in advanced childhood or adulthood.
The genes in the human body provide the information needed for the proteins synthesis responsible for regulating vital events in the body. Neurological disorders can occur as a result of harmful changes (mutations) in genes. In most cases, these mutations are inherited and passed on from generation to generation. In some cases, a mutation randomly occurs in a family member and is not passed on to the next generation. Genetic testing and genetic counseling provide information about the inheritance pattern of the mutation that causes the disease.

Neurogenetic disorders may be caused by a problem in a single gene, or in some cases, they may exhibit a complex structure associated with dozens of genes and environmental factors. There are many different methods and types of tests to detect genetic problems. Applying the correct test in the correct order is very important in reaching an accurate and timely diagnosis. The tests to be applied should be determined as a result of a detailed evaluation of the patient and family history, accompanied by genetic counseling.
What does genetic testing do?
Diagnoses or confirms the diagnosis
Helps refer patients to appropriate treatment and care services
Helps protect patients from complications by predetermining possible symptoms
Identifies family members at risk
Identifies the risks and options for families planning to have a child
