Drug-induced Psychosis
Drug-Induced Mental Disorder

Numerous substances can induce psychotic symptoms, including hallucinogenic drugs, opioids, sedative-hypnotics, amphetamines, cocaine, but also agents such as antiepileptics and antiparkinsonian drugs. The diagnosis can be made by confirmation of typical symptoms and through patient history.

Presentation

The clinical presentation of drug-induced psychosis understands the presence of delusions and/or hallucinations [1]. Most frequent delusions are of the persecutory type, while grandiose, referential, erotomanic, nihilistic and somatic types have also been described [1]. On the other hand, an onset of vivid and clear hallucinations, either auditory (more common) or sensory, is also the main feature of psychosis [1]. The onset of symptoms significantly varies depending on the substance. For example, patients who inhale large amounts of cocaine can develop symptoms within minutes, whereas sedative-hypnotic drugs and alcohol can induce psychosis after a prolonged period of use [1] [2]. Methamphetamine and cocaine-induced psychosis typically presents with delusions of persecution and visual hallucinations that last for a short period of time, but relapses have shown to occur within one week or one month after the substance abuse [3]. A similar presentation is seen across other causes, but paranoia, distortion in the perception of time and feelings of depersonalization have been reported in patients who develop psychosis after use of hallucinogenic substances, such as cannabis or lysergic acid diethylamide (LSD) [1] [4]. Moreover, opioid intoxication is characterized by profound euphoria, while withdrawal can either lead to agitation, gastrointestinal irritation, and craving, or to depression and anhedonia [4]. Drug-induced psychosis can also occur in patients who are taking antiepileptic and antiparkinsonian drugs [5] [6], which can mislead the physician toward substance abuse.

Psychiatrical

  • Visual Hallucination

    RESULTS: A total of 157 of 160 patients had hallucinations, with visual hallucinations being the most common (97% of subjects), followed by auditory (48%), tactile (23%), and olfactory (16%). [ncbi.nlm.nih.gov]

    hallucinations, intermittent memory impairment, mutism, disturbances of body image, delusions, apathy, and hypomania. [doi.org]

    This same patient described vivid visual hallucinations, the ability to “see in all four quadrants,” delusions of telepathy, and paranoid thoughts that others wanted to kill him. [primarypsychiatry.com]

    While some patients may be experiencing mood swings during withdrawal, and certain drug abusers could exhibit some of the telltale signs of psychosis — like visual hallucinations — it isn’t full-blown psychosis if said hallucinations are merely occurring [theoakstreatment.com]

  • Aggressive Behavior

    Blunted affect was milder in users than in non-users, whereas hostility and aggressive behavior was significantly more severe in users than in non-users. [doi.org]

    Confused thoughts result in confused speech that may not make any sense. [sovteens.com]

    Six did not (five on clozapine, one on olanzapine) because of confusion, erratic behavior, and increased hallucinations. No crossover failure had worsened PD except for increased tremor in one. [ncbi.nlm.nih.gov]

    This psychosis can last up to a few days, and is often characterized by hallucinations, delusions, memory loss and confusion. This usually results from prolonged or heavy street-drug use; and it responds well to treatment. [earlypsychosis.ca]

    Normally this kind of psychotic symptoms (Transient) can last for a few days until detoxing off the drug and is often characterized by delusions, memory loss, confusion and sometimes hallucinations. [thewellnessseeker.com]

    Confused thinking : Everyday thoughts can become confused, making sentences unclear or hard to understand. A person might find it hard to concentrate, follow a conversation or remember things. Thoughts can seem to speed up or slow down. [headspace.org.au]

  • Agitation

    These symptoms, plus agitation and hostility, may ultimately be the best measure of DIP in patients with PD. [ncbi.nlm.nih.gov]

    Upon presentation, he demonstrated echolalia, paranoia, flight of ideas, and psychomotor agitation. The patient remained agitated for the first 2 days of hospitalization. He attempted to barricade himself in his room. [doi.org]

    Moreover, opioid intoxication is characterized by profound euphoria, while withdrawal can either lead to agitation, gastrointestinal irritation, and craving, or to depression and anhedonia. [symptoma.com]

  • Irritability

    The person can seem excited, depressed or irritable for little or no reason obvious to others. Symptoms of psychosis are different for everyone. They might not be present all the time, have different causes and can change over time. [headspace.org.au]

  • Excitement

    Hoops had 1 case of mental excitement among 1,207 cases; Briercliffe 15 cases of delirium among some hundred persons taking mepacrine. Field estimated the incidence of mepacrine psychosis to be less than 01 per cent. of cases treated. [doi.org]

    Excessive nervous system excitability during periods of abstinence from alcohol is related to the effect of alcohol on the number and function of brain receptors. Etiology Ethanol interacts with GABA receptors, enhancing activity. [emedicine.medscape.com]

Workup

Current diagnostic criteria of drug-induced psychosis involve the following findings [1]:

  • The onset of symptoms during or soon after an introduction of a harmful substance, or exposure to a medication that can provoke such symptoms.
  • An absence of other signs and symptoms that may point to another cause, including the onset of symptoms before the use of suspected drugs, a prolonged duration of complaints (about 1 month) after cessation of use, or their presence in the setting of acute withdrawal.
  • Appearance of symptoms in time not related to delirium
  • Significant distress and impaired daily functioning caused by symptoms.

Once a presumptive diagnosis is made, it is necessary to determine the substance that is responsible for the development of symptoms. For this reason, an adequate and thorough patient history is considered to be the most important part of the diagnostic workup, which can reveal recent use of particular medications or substances [1] [7]. Preferably, hetero-anamnestic data should be obtained, involving both the family and friends, as the patient may often refrain from admitting substance abuse. If the cause remains undetermined, routine toxicology screening of urine for recreational drugs, alcohol testing, thyroid function tests, a basic metabolic panel and a thorough workup of the central nervous system (lumbar puncture, computed tomography of the endocranium) may be performed [2] [8].

Treatment

However, patients who do not respond to clozapine monotherapy can be given adjunctive treatment with ECT. [ncbi.nlm.nih.gov]

Recovery support groups are also usually incorporated into treatment and recommended as an ongoing relapse prevention strategy once treatment ends. [greenhousetreatment.com]

He said the stabbing likely would never have happened if Everman had received medication and treatment earlier. [mailtribune.com]

Prognosis

The prognosis for alcohol-induced psychosis is less favorable than earlier studies had speculated. However, if the patient can abstain from alcohol, the prognosis is good. [ncbi.nlm.nih.gov]

These papers cover the problems with long-term use, the supersensitivity psychosis, the fact the prognosis of schizophrenia is much better than has been claimed, that many people do fine going off meds, that prognosis is poorer for those on long term [forums.studentdoctor.net]

The prognosis for alcohol-related psychosis with treatment is considered good, with only 10-20% of psychosis cases becoming chronic. [emedicine.medscape.com]

Etiology

It is characterized by hallucinations, paranoia, and fear. [1] [2] [3] Etiology There are a variety of hypotheses to describe the etiology of alcohol-induced psychosis, but none of them can fully explain the development of acute or chronic hallucinations [ncbi.nlm.nih.gov]

Advocacy for mental illness must include the consideration of underlying etiological factors of psychiatric symptoms. [psychoticdisorders.wordpress.com]
