Abstract:
Propriospinal myoclonus (PSM) is a rare type of movement disorder in which the myoclonic jerks are present or intensified in supine position. Arising from a thoracic or abdominal generator, the movements propagate rostrocaudally as per the spinospinal conduction velocity. Routine neuroimaging and electrophysiology being normal in most instances, it is frequently interpreted as psychogenic. We present a case of PSM which will throw ample light on the pathophysiology, approach and dilemmas in treatment.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
