“…However, for establishing an accurate differential diagnosis, it should be noted that olfactory dysfunctions might represent clinical manifestations of temporal lobe epilepsy. In a population-based study olfactory hallucinations have been reported as associated with anxiety and stressful life events 32. In a study with veterans, increased distress has been found to be linked to specific smells experienced during traumatic episodes 33.…”

Burning mouth syndrome (BMS) is a rare but serious medical condition with important psychiatric comorbidity and specific psychological correlates. Psychopathology related with BMS represents a real challenge for clinical decision-making. In this case, depression is the leading psychiatric diagnosis associated with patient’s BMS somatic pain and is driven by anxiety and a dissociative functioning. Facing a complex psychosomatic symptomatology, we offer new clinical perspectives for the screening of psychological traits of BMS. Moreover, we highlight the need to foster interdisciplinarity to improve differential diagnosis and defining an optimal care path. This case report stimulates a reflection on management challenges for the consultation–liaison psychiatry and shows the importance of a person-centred approach when communicating the diagnosis.

“…Olfactory hallucination is an uncommon type of hallucination in which the individual reports olfactory perceptions in the absence of chemical stimuli. Olfactory hallucination has been reported in 4.2–14.5% of the general population ( 1 , 2 ). In more than half of affected individuals, olfactory hallucination occurs together with auditory, visual, or tactile hallucinations ( 2 ).…”

Olfactory hallucinations, similar to other psychotic-like experiences, are more common in young individuals (< 40 years) with less education who have been exposed to alcohol and drugs or who have experienced stressful and traumatic events ( 2 ).…”

Olfactory hallucinations, similar to other psychotic-like experiences, are more common in young individuals (< 40 years) with less education who have been exposed to alcohol and drugs or who have experienced stressful and traumatic events ( 2 ). Olfactory hallucinations have been observed in various neurological disorders, such as Alzheimer’s disease ( 3 ), Parkinson’s disease ( 4 ), epilepsy ( 5 ), and migraine ( 6 ), as well as in psychological disorders, such as schizophrenia ( 7 ), depression ( 8 ), bipolar disorder ( 9 ), and substance abuse ( 10 ).…”

“…People having health anxiety are mainly worried about and inaccurate interpret their body symptoms and might present psychotic-like symptoms, such as hypochondria ( 19 ). Furthermore, olfactory hallucinations may increase the likelihood of developing psychopathology: patients with olfactory hallucination develop symptoms of mood disorders whose severity correlates with severity of olfactory loss ( 2 ).…”

BackgroundOlfactory hallucination refers to olfactory perception in the absence of chemical stimuli. Although it has been associated with many neurological and psychotic disorders, it has rarely been reported as the first and only symptom in patients with anxiety disorder, and its treatment remains inadequate.Case summaryA 66-year-old woman who had been experiencing gradually worsening olfactory hallucinations for almost 4 years was diagnosed with generalized anxiety disorder. Olfactory hallucination disappeared after treatment with anti-anxiety drugs.ConclusionOlfactory hallucination can be the first and only symptom in patients with anxiety disorder and may be effectively treated with anti-anxiety medication. In fact, it can precede the diagnosis of anxiety disorder by several years.
