Exaggerated Startle Response: Causes, Symptoms, Treatment, Recovery, Yoga

What is Exaggerated Startle Response?

Exaggerated startle response is considered as an atypical inherited neurological disorder which may act on the toddlers, kids and even adults. Person, affected by the ailment of exaggerated startle response have sudden and high startle reactions such as body spasms or eye blinking to unexpected or sudden noise, touch or movement.

What is Exaggerated Startle Response?

Hypertonia or severe muscle strain or stiffness is observed in the individuals who are affected with exaggerated startle response. Hypertonia stops voluntary movement of the person’s muscles and turns the affected individual stiff just like a piece of wood without losing his or her consciousness.

In addition to hypertonia, hyperreflexia or exaggeration of reflexes and gait or an unbalanced technique of walking may arise in people with exaggerated startle response. Though, exaggerated startle response is an ADT (Autosomal Dominant Trait) by heredity, but it may be autosomal recessive and in rare case, X-linked heritage is found.

In most of the cases, exaggerated startle response is misdiagnosed as one of the types of epilepsy and so it takes a long time to find out the exact diagnosis. The treatment for exaggerated startle response is comparatively uncomplicated and related to the use of the medicines of anti-spastic and anti-anxiety. Cognitive therapy and physical therapy (PT) are considered as additional treating options.

What are Body Spasms?

Twitching of muscle that is also known as muscle fasciculation is seen as small contractions of muscles in the body. Muscles of human beings are built of nerves, tissues and fibers. So, while a nerve is damaged or stimulated, the fibers of the muscle twitch.

Though, individuals experience twitching in their body from time to time and these are very minor, but some kinds of twitching can be a symptom of the condition of nervous system and it is better to check with the doctor.

Causes of Exaggerated Startle Response

Generally, exaggerated startle response is classified as genetic disease, but some other disorders imitate the symptoms of exaggerated startle response.

In majority of the cases, the cause of exaggerated startle response is hereditary, because this disorder is considered as autosomal dominant trait. However, it also can follow X-linked inheritance or autosomal recessive. Mutations of the genes such as GLRA1, GLRB, SLC6A5, X-linked (ARHGEF9), GPHN are related to this condition. Most of the exaggerated startle response affected persons are due to the mutation of SLC6A5, GLRA1 gene or their parents are affected by it.

Genes which are responsible for exaggerated startle response, produces glycine protein and glycine weakens the activities of cells of the nerve in the spinal cord and in the brain. It is identified as “inhibitor transmitter”. When the glycine receptors are damaged or hampered the cells of the nerve hang-up and consequently respond to stimuli excessively and very easily.

DGD (Dominant Genetic Disorders) happens when even a single unnatural gene is necessary to cause a particular disease. The affected person may get the unnatural abnormal gene by hereditary from their parent; in addition, it may occur due to gene change (mutation). The possibility of passing the abnormal gene from affected father or mother to their child is 50% during the pregnancy. The risk is the equal for men and women.

Even the physicians are not sure why some people get exaggerated startle response. Just like in most of cases of mental health problems, exaggerated startle response is the result of a complex mixture of the followings:

  • Risks of inborn mental health, such as high risk of depression and anxiety.
  • Negative experiences in life, including the severity and amount of trauma the affected person has passed through since his or her early age or childhood.
  • Inherited characteristics of your personality- which is identified as your temperament.
  • The mode or system of the affected person’s brain that regulates the hormones and chemicals in the body of that particular person releases at the time of responding to trauma or stress.

Most common leading causes for developing exaggerated startle response:

  • Exposure to combat
  • Negligence in childhood and physical abuse.
  • Sexual violence
  • Physical assault.

In addition, there are also numbers of traumatic or shocking events that also lead to the problem of exaggerated startle response, for example, natural disaster, terrorist attack, fire accident, plane crash, car accident, robbery, mugging, life-threatening medical diagnosis, kidnapping, torture and numerous severe events.

Most Affected People by Exaggerated Startle Response

Exaggerated startle response which is a rare genetic disorder is found at the time of birth and it affects both men and women. In some cases, the disorder takes time to flourish; it may be belated to the childhood or adulthood. In the United States, about 1 person in 40,000 people is affected by exaggerated startle response.

  • Startle Epilepsy: In startle epilepsy the muscles of the affected person contracts briefly and the body responses to sudden movement or noise. The patients fall down frequently being startled and other symptoms of spasm also are expressed.
  • Tic Disorder or General Anxiety: Disorders such as tic or general anxiety and other conditions which are related to startle are considered as having related symptoms, such as SPS (Stiff Person Syndrome) is noticed in aged persons (normally between 50 years and 60 years) and it is accompanied with progressive and prolonged firmness and periodic body spasms.

Signs and Symptoms of Exaggerated Startle Response

There are severe and mild types of exaggerated startle response. Unusually severe startle response to unexpected or sudden touch, noise and movement are characterized as severe type of exaggerated startle response. HRR or exaggerated head-reaction response, myoclonic jerks or spastic jerking movements, falling stiffly on the floor and still being awake/conscious and these tendencies occur when the individual has exaggerated startle response.

Below mentioned are the signs and symptoms of exaggerated startle response:

  • A patient of exaggerated startle response may experience jerking movement when he is trying to sleep.
  • High muscle strain or hypertonia (firmness) is very much common in those infants who are suffering from exaggerated startle response, particularly at the time of birth. Babies, affected by exaggerated startle response cannot move much, and if they want to do so, they usually move leisurely which is called hypokinesia.
  • Excess body reflexes/hyperreflexia, intermittent apnea or intervallic breathing or/and gait- unbalanced walking with slight wide-based posture are the other symptoms of those infants and also the adults suffering from exaggerated startle response. A few infants have dislocated hip at the time of their birth. Additionally, inguinal hernias or hernias in the lower abdomen are also common.
  • In the case of minor or mild type exaggerated startle response, the affected individuals experience irregular or changeable startle response with none or a few other symptoms. In infants, fever can bring this type of exaggerated startle response and in the adults; the intensity of the responses of startle may be influenced by anxiety or stress.

  • Inability to move for a time period following the shock.

One of the effective tests of exaggerated startle response is electromyography and the other is Electroencephalography. The former records the electrical muscle impulse and the latter measure the brain electrical activity.

The primary step for testing the molecular genetics for those who already detected the diseases is mutation test in SLC6A5 genes and GLRA1. The analysis of the sequence of genetic materials ARHGEF9 can be believed in men without identifying the mutations of SLC6A5 or GLRA1, especially in the case of cognitive injury and the presence of epilepsy. If transformations or mutations cannot be identified, the genetic testing of the molecule for the mutations in the genetic material in the GPHN and GLRB can be granted for consideration.
