Hypnagogic and hypnopompic hallucinations during amitriptyline treatment
Acta Psychiatrica Scandinavica
|October 1, 1980
Summary
Amitriptyline treatment can cause hypnagogic or hypnopompic visual hallucinations. These benign hallucinations are temporary and patients should be informed to avoid premature treatment termination.
Area of Science:
- Neuroscience
- Pharmacology
- Psychiatry
Background:
- Amitriptyline is a commonly prescribed antidepressant.
- Visual hallucinations are not a typical side effect of amitriptyline.
Observation:
- Four patients on amitriptyline reported experiencing hypnagogic or hypnopompic visual hallucinations.
- These hallucinations were vivid, projected into external space, and initially perceived as real.
Findings:
- Patients quickly recognized the unreality of the hallucinations.
- The phenomena may be linked to amitriptyline's effects on brain function, sleep patterns, and clinical recovery.
Implications:
- Informing patients about these benign visual disturbances is crucial.
- This knowledge can prevent unnecessary discontinuation of amitriptyline therapy.

01:23Sedatives and Hypnotics: Overview
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:06Altered States of Awareness
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

01:17Sleepwalking 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...

01:07Narcolepsy
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
