According to a study on sleep disturbances in the Journal of Neural Transmission, a hypnic jerk occurs during the non-rapid eye movement sleep cycle and is an "abrupt muscle action flexing movement, generalized or partial and asymmetric, which may cause arousal, with an illusion of falling". [13]
Myoclonus is a brief, involuntary, irregular (lacking rhythm) twitching of a muscle, a joint, or a group of muscles, different from clonus, which is rhythmic or regular. Myoclonus (myo-"muscle", clonus "spasm") describes a medical sign and, generally, is not a diagnosis of a disease.
The primary disorder is benign essential blepharospasm, in which term the qualifier essential indicates that the cause is unknown. Blepharospasm may occur as secondary to conditions including dry eyes and other specific ocular disease or conditions, Meige's syndrome and other forms of dystonia, and Parkinson's disease and other movement disorders.

The three main signs of hyperekplexia are generalized stiffness, excessive startle response beginning at birth, and nocturnal myoclonus. [5] Affected individuals are fully conscious during episodes of stiffness, which consist of forced closure of the eyes and an extension of the extremities followed by a period of generalised stiffness and uncontrolled falling at times.

Weakness/paralysis of a limb or the entire body (hysterical paralysis or motor conversion disorders) Impairment or loss of speech (hysterical aphonia) Difficulty swallowing or a sensation of a lump in the throat; Urinary retention; Psychogenic non-epileptic seizures or convulsions; Persistent dystonia; Tremor, myoclonus or other movement disorders
Cancer is the number-one disease-related killer of cats and dogs. Many cancer symptoms in cats are subtle and can be caused by another condition, but if you notice any of the following potential ...
Palatal myoclonus. The myoclonic triangle (also known by its eponym Triangle of Guillain-Mollaret or dentato-rubro-olivary pathway) is an important feedback circuit of the brainstem and deep cerebellar nuclei which is responsible for modulating spinal cord motor activity. [1] [2] The circuit is thus composed: [2]
