Deafness – Sensitivity disorder

A sensitivity disorder is a temporary irritation or permanent damage to the nerve. This leads to misdirected sensations in case of external irritations of the body of the affected person. Just as there can be many different causes for the development of the sensory disorder, there are a large number of forms of sensory disorder.

Therefore, the diagnoses and thus the treatment options are also very diverse. Unfortunately, there is no prophylaxis (prevention) against sensitivity disorders that can guarantee to prevent deafness. A sensitivity disorder leads to a changed perception of external stimuli. This disturbance is caused by a change in the nerves.

Forms of sensory disorder

Seven different stimuli are distinguished: If a sensitivity disorder is present, these stimuli are perceived as either unpleasant or even painful (so-called dysesthesia), stronger (in the case of hyperesthesia) or weaker (in the case of hypaesthesia) than usual. A complete sensory disturbance is also possible so that the stimulus cannot be perceived at all (anesthesia). Another form of sensory disorder is paresthesia, in which the sensation is present but not triggered by a corresponding stimulus.

This is generally known from the harmless case when your arm or leg has “fallen asleep”, i.e. you feel an “ant walk” over the area, although nothing is walking along it. Sensitivity disorders that last longer than a “fallen asleep leg/arm” are generally to be taken very seriously, as they can have far-reaching consequences. If the person affected is under anesthesia, i.e. an absence of pain sensation, an accidental injury may go unnoticed and thus cannot be adequately treated. In this case, bleeding to death, infection of the wound and thus long-term “mutilation” are possible consequences.

  • Sensation of touch
  • Temperature sensation
  • Vibration sensation
  • Feeling of pain
  • Sensation of movement
  • Feel the situation
  • Feeling of strength

Causes

A sensitivity disorder is caused by a functional disorder of the nerves, therefore the cause of this disorder must also be sought in the area of nerve function. Migraine is often caused by a temporary irritation of the nerves. Further restrictions of the regular nerve function can be circulatory disorders (for example, as a slight variant of the “fallen asleep arm”), infestation by viruses (for example herpes viruses) or treatment with drugs that lead to permanent nerve damage. Possible causes of circulatory disorders, which can then lead to nerve damage, include the following: General illnesses that can lead to sensitivity disorders are

  • Burns
  • Stroke
  • Diabetes
  • Tumors (especially in brain and spinal cord)
  • Neurological diseases (e.g. Parkinson’s or multiple sclerosis)
  • Herniated disc ->
  • Circulatory disorders
  • Pinched nerve
  • Alcohol abuse
