Understanding the mental health burden of COVID-19 in the United Kingdom.

This article outlines the mental health burden of COVID-19 in the United Kingdom population, and presents preliminary evidence of less common psychiatric issues, such as paranoia and hallucinations, to which vulnerable groups in the U.K. population may be more vulnerable. It is argued that cognitive-behavioral therapy, with components of mindfulness, should be part of the therapeutic response. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Cotard Syndrome.

Cotard's syndrome is often described as the delusional belief that one is dead or non-existent. However, Jules Cotard's initial description (1880) of the "delusion of negations" was much richer and also involved delusions and claims of immortality and enormity, feelings of damnation, and illusions of bodily dissolution and transformation. Alternatively conceived as an extreme case of depression, hypochondria, or psychosis, the condition is considered rare and remains poorly understood. Cotard himself provided a taxonomy and several explanations for the condition, focusing on its distinction from classical persecutory delusions and suggesting that it could be a kind of reversed grandiosity. He proposed a psychosensory basis in the dissolution of mental imagery, which he then extended to a more general psychomotor impairment of volition. Other early authors highlighted a disorder of the bodily self, and more recent theories postulated an impairment of right hemispheric functions, leading to perceptual and somatosensory feelings of unreality, which coupled with reasoning impairments and an internalized attributional style led in turn to beliefs of non-existence. However, despite its striking presentation and its relevance to our understanding of self-awareness, Cotard's syndrome remains an elusive condition, rarely reported and poorly researched.

Spice: a legal marijuana equivalent.

Spice, an herbal mixture containing synthetic cannabinoids, is a legal drug increasingly abused by adolescents and young adults for its narcotic-like effects. A paucity of English language literature exists on the clinical effects of Spice use. A case report of substance-induced psychosis and a summary of available literature follows later.

A possible role for Progressive Muscle Relaxation in the treatment of persecutory ideation.

Persecutory ideation is one of the most commonly reported psychiatric symptoms in individuals with schizophrenia and is associated with significant patient distress and impairment. Therefore, much attention has recently been devoted to theoretical explanations of persecutory ideation that can help inform and guide patient care. A cognitive model of persecutory ideation suggests that individuals with psychosis who experience anxiety along with other stressors are at increased risk for developing intense "threat" or persecutory beliefs. Correlational studies have found evidence for this proposed link between anxiety levels and the persistence, distress levels, and degree of conviction associated with persecutory ideation. Importantly, recent research has found support for a possible prospective/causal role for anxiety in the generation and maintenance of paranoid beliefs. Existing interventions for persecutory ideation consist of pharmacological treatments that have variable efficacy and often entail serious side-effects, and cognitive behavioral treatments (CBT) that target persecutory thoughts, but are often unavailable, require high level of clinician expertise, and may be difficult to conduct with patients who are cognitively impaired or apprehensive about openly exploring their paranoid beliefs. Given the empirical support for a prospective relationship between anxiety and persecutory ideation, it is reasonable to predict that clinicians could impact persecutory ideations indirectly by making good use of existing evidence-based interventions for anxiety. Progressive Muscle Relaxation (PMR) is an effective method for reducing physiological arousal and treating various anxiety disorders, and has been shown to be feasible with patients with psychosis. We offer that exportability and ease of use makes PMR a promising intervention for mental health practitioners to target anxiety precipitating persecutory ideation. We hypothesize that PMR could be used to help ameliorate anxiety in patients who are at risk or already experiencing persecutory ideation, subsequently reducing the frequency, level of conviction, and distress associated with persecutory thoughts. Our hypothesis could be tested through feasibility and randomized control trials of PMR for treatment of persecutory ideation in individuals with schizophrenia. We expect the relationship between PMR and persecutory ideation will be mediated by reduction in anxiety. Potential advantages of examining our hypothesis include identifying a viable, efficacious, cost-effective novel intervention for paranoia in patients with psychosis. In addition, PMR could be easily facilitated by practitioners with varying levels of training and integrated with other existing interventions for persecutory ideation.

Intracranial hypertension in a dieting patient.

We report a case of encephalopathy with paranoid psychosis in association with intracranial hypertension. This occurred in a patient whose diet consisted almost solely of walnuts, ginseng tea, and vitamin A supplements. The patient was found to be severely iron- and vitamin B12-deficient. She was vitamin A toxic. Venous sinus thrombosis was also present. Symptoms remitted with serial lumbar punctures, normalization of diet, and repletion of vitamin B12 and iron stores. Physicians should be alerted to the possibility of a potentially confusing clinical presentation with coexistent and seemingly mutually exclusive neurologic conditions in patients with extremely restricted or fad diets.

Pellagra: unusual cause of paranoid delirium in dialysis.

A 60-year-old woman treated by maintenance haemodialysis refused to take part of the usual vitamin supplements for many years. After an intercurrent illness with profound malnutrition, she developed a paranoid delirium and some behavioural disorders; concomitant diarrhoea and a skin rash were noted. Parenteral nicotinamide (500 mg/day) resulted in a complete recovery from the mental disorders after five days. Other causes of mental disturbance as a result of dialysis could be ruled out. However an asymptomatic underlying hypothyroidism may have been one of the conditioning factors as well as the failure to administer nicotinamide supplements during an acute illness. Neurological pellagra could thus be considered as a rare but reversible cause of mental disorders in patients on maintenance haemodialysis.

Induced hearing deficit generates experimental paranoia.

The development of paranoid reactions was investigated in normal people experiencing a temporary loss of hearing. In a social setting, subjects made partially deaf by hypnotic suggestion, but kept unaware of the source of their deafness, became more paranoid as indicated on a variety of assessment measures. The results support a hypothesizes cognitive-social mechanism for the clinically observed relationship between paranoia and deafness in the elderly.
