Signs and Symptoms in Psychiatry
Published in Mohamed Ahmed Abd El-Hay, Essentials of Psychiatric Assessment, 2018
Olfactory hallucination: false perception of smell usually experienced as an unpleasant smell. It may occur in schizophrenia or severe depressive disorders, but it should also suggest temporal lobe epilepsy or irritation of the olfactory bulb or pathways by a tumor.

Smell may be lost (anosmia), diminished (hyposmia), perverted (parosmia), distorted (dysosmia) or unpleasant (cacosmia). Olfactory hallucinations are most commonly reported as part of the aura of complex partial seizures. These are usually unpleasant, very brief and may arise in the uncinate lobe. Olfactory hallucinations may also occur in psychiatric disorders.

Overall hypnotizability level measured as the total EHS-CF score was negatively correlated with age (rho = −0.271, p = .046). In the LOW group, there was a negative correlation between the overall hypnotizability level and Masculinity/Femininity (rho = −0.452, p = .018). When referring to individual EHS-CF items, arm heaviness/immobilization was negatively correlated with Psychasthenia (rho = −0.425, p = .027), Schizophrenia (rho = −0.389, p = .045), Cynicism (rho = −0.481, p = .011), Dysfunctional negative emotions (rho = −0.443, p = .021), and Psychoticism (rho = −0.461, p = .016), and positively correlated with Ego Strength (rho = 0.442, p = .021). The rose olfactory hallucination was positively correlated with Disconstraint (rho = 0.448, p = .019). In the MID-HIGH group, there was no association between the overall hypnotizability level and the MMPI-2 scales. By contrast, arm heaviness/immobilization was negatively correlated with Low Positive Emotions (rho = −0.412, p = .029) and positively correlated with Hypomanic Activation (rho 0.396, p = .037) and Aggressiveness (rho 0.594, p = .001). The rose olfactory hallucination was positively correlated with Schizophrenia (rho = 0.393, p = .039). In both groups, there was no association between arm lightness/levitation, imagery involvement/dissociation, and the MMPI-2 scales.
Treating hallucinations in Parkinson’s disease

Auditory hallucinations are less frequent in PD (reported prevalence of 22% to 48%) [9] and may accompany hallucinations across other modalities [4,15]. They are rarely paranoid or imperative in nature [15], usually involving simple noises such as rustling, voices and music [9,11]. Olfactory hallucinations occur in around 10% of patients with PD with or without hyposmia or cognitive impairment and can precede the development of motor symptoms by one to five years [11,16]. Tactile hallucinations though uncommon, are reported in PD typically accompanying hallucinations in other modalities [11]. Finally, there are only a few case reports of gustatory hallucinations in PD [11].
