Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Nightmares and Night Terrors

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.
Nightmares often...

Restless Leg Syndrome and Night Terrors

Restless Leg Syndrome and Night Terrors

Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

Sleepwalking and Sleep Talking

Sleepwalking and Sleep Talking

Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Summary

Prominent sleep-related hallucinations, initially hypnopompic, can become distressing. A low dose of olanzapine effectively treated these severe auditory hallucinations, suggesting a potential therapeutic option.

Area of Science:

Neurology
Psychiatry

Background:

Sleep-related hallucinations, hypnagogic and hypnopompic, are typically brief phenomena in healthy individuals.
These hallucinations can be associated with conditions like narcolepsy when prominent or distressing.

Observation:

A case presented with severe hypnopompic auditory hallucinations.
These hallucinations evolved into continuous, distressing experiences resembling schizophrenia-like hallucinations.

Findings:

The patient's severe, persistent auditory hallucinations showed a positive response to a low dose of olanzapine.
This suggests olanzapine may be effective in managing complex sleep-related hallucinations.

Implications:

This case highlights that severe sleep-related hallucinations can mimic primary psychiatric disorders.
Low-dose olanzapine may offer a treatment strategy for refractory hypnopompic hallucinations.
