About Hereditary hyperekplexia

What is Hereditary hyperekplexia?

Hereditary hyperekplexia is a rare inherited neurological disorder characterized by an exaggerated startle response and muscle stiffness. It is caused by a mutation in the GLRA1 gene, which is responsible for the production of the neurotransmitter glycine. Symptoms of the disorder include an exaggerated startle response to sudden noises or movements, muscle stiffness, and difficulty sleeping. In severe cases, the disorder can cause seizures and breathing difficulties.

What are the symptoms of Hereditary hyperekplexia?

The main symptoms of Hereditary hyperekplexia include:

-Exaggerated startle response to sudden noises or movements
-Stiffness or rigidity of the body, especially in the arms and legs
-Difficulty sleeping due to frequent startle responses
-Difficulty feeding due to difficulty swallowing
-Frequent falls due to difficulty controlling muscle movements
-Delayed motor development
-Frequent yawning
-Breathing difficulties
-Seizures

What are the causes of Hereditary hyperekplexia?

Hereditary hyperekplexia is caused by mutations in the GLRA1, GLRB, and SLC6A5 genes. These genes provide instructions for making proteins that are involved in the transmission of nerve signals. Mutations in these genes lead to an overactive startle response, which is the main symptom of hereditary hyperekplexia.

What are the treatments for Hereditary hyperekplexia?

1. Medication: The mainstay of treatment for hereditary hyperekplexia is the use of benzodiazepines, such as clonazepam, to reduce the frequency and severity of startle responses.

2. Physical Therapy: Physical therapy can help to improve muscle tone and coordination, as well as reduce the risk of falls.

3. Surgery: In some cases, surgery may be recommended to reduce the severity of startle responses.

4. Dietary Changes: Dietary changes, such as avoiding caffeine and other stimulants, may help to reduce the severity of startle responses.

5. Genetic Counseling: Genetic counseling can help to provide information about the condition and the risks associated with it.

What are the risk factors for Hereditary hyperekplexia?

1. Family history: Hereditary hyperekplexia is an inherited disorder, so having a family history of the condition increases the risk of developing it.

2. Genetic mutations: Certain genetic mutations can increase the risk of developing hereditary hyperekplexia.

3. Age: Hereditary hyperekplexia is more common in infants and young children.

4. Gender: Hereditary hyperekplexia is more common in males than females.

Is there a cure/medications for Hereditary hyperekplexia?

Yes, there are medications available to treat Hereditary hyperekplexia. These medications are used to reduce the frequency and severity of startle responses. The most commonly used medications are clonazepam and sodium valproate. Other medications that may be used include benzodiazepines, anticonvulsants, and muscle relaxants. It is important to note that medications may not be effective in all cases and may have side effects. It is important to discuss the risks and benefits of any medication with your doctor before starting treatment.
