This is because the vascular accident produces direct damage to those neurons that are responsible for the hormones that produce orexin. There is a registry of patients with vascular accidents, who subsequently present an alteration in the organism characterized by including cataplexy. Injuries to the head or spine may be sufficient reason to trigger episodes of cataplexydue to the reasons stated above.Įven malformations, considered tumors in both areas, lead to muscle weakness described in this disorder. Note: A brain tumorcan be the trigger for this situation, losing control of the muscles and also being possible an alteration in hormone levels as a result of these malformations. One of the reasons for cataplexy is the inhibition of certain neuronswith motor functions along the spinal cord. Important: There is research that shows that exposure to emotions of this type automatically causes a decrease in muscle tone, but clearly, due to certain conditions, in cataplexy the degree of severity is increased. These emotionsinclude: shame, anger, laughter, fear, among others. These episodes are usually brief, and motivated the individual to face sudden strong emotions. Hormone deficiencyĪ hormonal deficiencyof orexin or hypocretin, leads in the person to the appearance of cataplexy picturesbecause these hormones are those that fulfill fundamental roles in our body, such as maintaining alertness and wakefulness. The causes that trigger these episodes can be varied, so they will be exposed and described below, facilitating their identification and understanding. Cataplexyis defined as the second most recurrent symptom against narcolepsy, where an imbalance occurs in the person between the inhibitory and excitatory systems, usually after an emotional stimulus, causing a temporary reduction in muscle tone. (1)įun fact: The word cataplexycomes from a Greek that means “to bring down”, which translated to the sudden loss of muscle mass presented by patients with narcolepsy, which was taking shape with the description of the disorder, which is the temporary loss of musclestrength when facing strong emotions such as laughter, anger or embarrassment.
