An increase in neurotransmitters causes spasms to occur in the neck, resulting in spasmodic torticollis. [6] Studies of local field potentials have also shown an increase of 4–10 Hz oscillatory activity in the globus pallidus internus during myoclonic episodes and an increase of 5–7 Hz activity in dystonic muscles when compared to other ...

Intense physical activity can affect your core body temperature, which can cause chills. Muscle cramps, dizziness, fatigue, nausea, and vomiting might happen, as well.
A further assumption is that a low levels of serotonin can causes spasms in the cervical area. [1] A plausible explanation for the cricopharyngeal spasms is a lack of neurotransmitter preventing the central nervous system from detecting that the eosophagus is closed, so that the upper esophagus sphincter becomes, randomly, hypertonic.
Reflex syncope can occur in otherwise healthy individuals, and has many possible causes, often trivial ones such as prolonged standing with the legs locked. [citation needed] The main danger of vasovagal syncope (or dizzy spells from vertigo) is the risk of injury by falling while unconscious.
MMN usually involves very little pain; however, muscle cramps, spasms and twitches can cause pain for some people. MMN is not fatal, and does not diminish life expectancy. Many patients, once undergoing treatment, only experience mild symptoms over prolonged periods, though the condition remains slowly progressive.
Occipito-cervical junction This disorder may result from rheumatoid arthritis, causing the hypermobility of the connection between the neck and head, resulting in paralysis or pain. [6] Cerebrovascular disease Cerebrovascular disease is a type of cervical spine disorder that can cause tetraplegia. [7] Subaxial cervical spine [8] Atlanto-axial joint
