“…In at least two cases, the OHs were explicitly described as being repetitive (Diamond, Freitag, Prager, & Gandi, 1985;Wolberg & Ziegler, 1982). The duration of the OHs varied from 5 min to 2 hours (Fuller & Guiloff, 1987;Wolberg & Ziegler, 1982). In all cases, the OH was attributed to an environmental cause, a point well made by Crosley and Dhamoon's patient, whose home was repeatedly investigated for "gas leaks."…”

“…Of the nine cases reported in depth in the literature, six reported unpleasant odors (Ardila & Sanchez, 1988;Crosley & Dhamoon, 1983;Fuller & Guiloff, 1987;Wolberg & Ziegler, 1982). In at least two cases, the OHs were explicitly described as being repetitive (Diamond, Freitag, Prager, & Gandi, 1985;Wolberg & Ziegler, 1982).

“…In all cases, the OH was attributed to an environmental cause, a point well made by Crosley and Dhamoon's patient, whose home was repeatedly investigated for "gas leaks." As to the cause of the OHs, in four cases more extensive physical investigations with EEG, olfactory tests, and brain imaging ruled out epilepsy or nasal pathology (Fuller & Guiloff, 1987;Wolberg & Ziegler, 1982).…”

Olfaction's unique cognitive architecture, the apparently inconsistent evidence favoring imagery, and its difficulty of evocation have led some to conclude that there is no capacity for olfactory imagery. Using three streams of evidence, we examine the validity of this claim. First, self-reports of olfactory imagery can resemble those obtained for actual perception. Second, imagining an odor can produce effects similar to actual perception. Third, olfactory perception and memory-based images can interact. A model of olfactory imagery is then presented that utilizes the same systems employed in actual perception, with similar constraints. This model is consistent with olfaction's unique information-processing capacities and can account for previous experimental inconsistencies on the basis of difficulty of evocation, a consequence of unstable access to semantic information. In sum, the evidence presented here is favorable to the existence of an olfactory imagery capacity.

“…Their mean age was 59 years, mean duration of disease 12 (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) years, mean duration of levodopa therapy 9 5 (1 5-19) years and mean stage of Hoehn and Yahr 3-4 when "off" and 2-4 when "on". All patients were known to respond to their first morning dose of 100 or 200 mg of oral levodopa plus decarboxylase inhibitor within 15 to 30 minutes and the mean duration of effect was 135 (90-120) minutes.…”

“…Patients with both temporal lobe epilepsy [14,24] and migraine headaches [48,49,50,51,52,53,54] also reported olfactory auras prior to seizure or headache pain onset, respectively. One group of authors related these phantosmias to trigeminal nerve activation [55].…”

Olfactory Hallucinations without Clinical Motor Activity: A Comparison of Unirhinal with Birhinal Phantosmia

Olfactory hallucinations without subsequent myoclonic activity have not been well characterized or understood. Herein we describe, in a retrospective study, two major forms of olfactory hallucinations labeled phantosmias: one, unirhinal, the other, birhinal. To describe these disorders we performed several procedures to elucidate similarities and differences between these processes. From 1272, patients evaluated for taste and smell dysfunction at The Taste and Smell Clinic, Washington, DC with clinical history, neurological and otolaryngological examinations, evaluations of taste and smell function, EEG and neuroradiological studies 40 exhibited cyclic unirhinal phantosmia (CUP) usually without hyposmia whereas 88 exhibited non-cyclic birhinal phantosmia with associated symptomology (BPAS) with hyposmia. Patients with CUP developed phantosmia spontaneously or after laughing, coughing or shouting initially with spontaneous inhibition and subsequently with Valsalva maneuvers, sleep or nasal water inhalation; they had frequent EEG changes usually ipsilateral sharp waves. Patients with BPAS developed phantosmia secondary to several clinical events usually after hyposmia onset with few EEG changes; their phantosmia could not be initiated or inhibited by any physiological maneuver. CUP is uncommonly encountered and represents a newly defined clinical syndrome. BPAS is commonly encountered, has been observed previously but has not been clearly defined. Mechanisms responsible for phantosmia in each group were related to decreased gamma-aminobutyric acid (GABA) activity in specific brain regions. Treatment which activated brain GABA inhibited phantosmia in both groups.
