Sopite syndrome

Sopite syndrome is a neurological disorder characterized by symptoms of drowsiness and mood changes, often associated with prolonged periods of motion. It is considered a subtype of motion sickness, although its symptoms and effects can be more debilitating and less well understood.

Symptoms

The primary symptom of Sopite syndrome is an overwhelming sense of fatigue or sleepiness. Other symptoms can include apathy, decreased levels of concentration, disinterest in work, and changes in mood. These symptoms can persist for several hours or even days after the motion has ceased.

Causes

Sopite syndrome is believed to be caused by prolonged exposure to motion, particularly in environments such as vehicles or boats where the motion is constant and unavoidable. The exact mechanism by which this occurs is not fully understood, but it is thought to involve a complex interaction between the vestibular system, which controls balance and spatial orientation, and the central nervous system, which regulates sleep and wakefulness.

Diagnosis

Diagnosis of Sopite syndrome is primarily based on the patient's symptoms and history of exposure to motion. There are no specific tests for the condition, and it is often underdiagnosed due to its similarity to other conditions such as chronic fatigue syndrome and depression.

Treatment

Treatment for Sopite syndrome primarily involves managing the symptoms and avoiding situations that trigger the condition. This can include strategies such as taking breaks from driving, using motion sickness medication, and practicing relaxation techniques. In severe cases, cognitive behavioral therapy may be recommended.
