Psychosis Atypical

Psychosis refers to an abnormal condition of the mind, often described as a loss of contact with reality. The two main symptoms of psychosis are hallucinations and delusions. The causes of psychosis have three main classifications: Psychological causes, General medical conditions and Substances.


  • Here we present the case of a patient suffering from delusions, which turned out to be caused by encephalitis secondary to a previously unknown HIV infection. A review of psychosis in HIV-infected patients is also presented.[ncbi.nlm.nih.gov]
  • She presented to us with psychotic symptoms but also noted to have many catatonic features, which were also present on previous presentations.[ncbi.nlm.nih.gov]
  • CASE PRESENTATION: Here, we present a case of a 15 year-old female adolescent with first-episode psychosis with anti-NMDA receptor encephalitis not related to tumor, which manifested with delusion, hallucinations, panic attacks, agitation, and neurological[ncbi.nlm.nih.gov]
  • The present study is a case series.[ncbi.nlm.nih.gov]
  • Participants were asked whether the action was presented verbally or non-verbally (action presentation type discrimination), and whether the action was performed or imagined (self-monitoring).[ncbi.nlm.nih.gov]
  • Myxedema psychosis is rarely the initial presenting symptom of hypothyroidism, especially in the absence of other abnormal clinical or laboratory findings.[ncbi.nlm.nih.gov]
  • Findings on neuroimaging were attributed to APS-associated thrombosis in most cases. Most patients had a complete resolution of psychotic symptoms. CONCLUSION: APS-associated psychosis is rare.[ncbi.nlm.nih.gov]
Abnormal Eye Movement
  • We will consider hallucinosis, abnormal eye movements, sensory attenuation deficits, catatonia, and delusions as various expressions of the same core pathology: namely, an aberrant encoding of precision.[ncbi.nlm.nih.gov]
  • Abstract A 73-year-old woman with no previous psychiatric history received clonazepam maintenance therapy for essential blepharospasm. Visual, auditory, and tactile hallucinations as well as paranoid delusions were documented.[doi.org]
  • A delusion is where a person has an unshakeable belief in something untrue.[nhs.uk]
  • The syndrome is quite stereotypic, with hallucinations being the most common, followed by delusions. While the hallucinations are usually not very bothersome, the delusions are typically paranoid in nature.[ncbi.nlm.nih.gov]
  • Psychosis is a symptom complex that may include hallucinations, delusions, disorders of thought, and disorganized speech or behavior.[ncbi.nlm.nih.gov]
  • Antipsychotic drugs, which reduce hallucinations and delusions and improve thinking and behavior, are helpful. How well a person does depends on the cause of the psychosis. If the cause can be corrected, the outlook is often good.[nlm.nih.gov]
Psychiatric Manifestation
  • According to the literature, this psychiatric manifestation resolves within 2 weeks of discontinuing the offending agent.[ncbi.nlm.nih.gov]
  • There is growing evidence that a proportion of psychosis/ psychiatric manifestations in children may be immunemediated, and physicians should consider this etiology in each presentation of first-episode psychosis.[ncbi.nlm.nih.gov]

  • Besides, other diagnostic workups failed to show any other reason for hepatitis. It is noteworthy that hepatitis with mildly elevated transaminase level is also a common finding in brucellosis [ 1 ].[karger.com]
