Hyperosmia - Wikipedia
Learn about hyperosmia, a heightened sense of smell, and its causes. Some neurologic conditions have also been linked to hyperosmia, including multiple Multiple sclerosis is known to affect senses like taste and smell. The close anatomical and functional connection between the orbitofrontal 9) at the Department of Psychiatry and the Taste and Smell Clinic of the University of .. acute sense of smell than healthy controls, independent of the season during . Of all the things we might associate with sense of smell, how long we The only physical condition that was a stronger predictor of death was.
This ambiguity is also the reason why 2-tailed testing was performed. To this effect, olfactory function in clinically euthymic patients with BD was assessed on both psychophysical phenyl ethyl alcohol odour thresholds, olfactory quality discrimination and odour identification and electrophysiological levels olfactory event-related potentials [ERP].
All participants were outpatients of the Department of Psychiatry. The study was performed in accordance with the Declaration of Helsinki concerning biomedical studies in human subjects.
All patients gave informed consent. Remission euthymia was defined as the absence of symptoms of depression, mania or mixed mania for a minimum of 3 months without recurrence. This was verified by both review of clinical records and interview with one of the authors S. Although self-reporting of manic symptoms may be limited by lack of insight, all our subjects acknowledged their bipolar illness, thus justifying the use of the SRMI instead of an observer-rated instrument. Patients were then divided into 2 groups: In the absence of a systematic instrument to assess event-triggered episodes, events considered to have triggered the last episode had been identified in the psychoeducational program for BD conducted at the hospital; they were documented in the patients' charts.
Many patients in group B reported that they had experienced similar events to those experienced by group A patients but that they had not been affected by them.
Demographic and illness-related parameters at baseline are summarized in Table 1. Patients differed with respect to their ages: However, changes to the sense of smell may trigger an increase in headaches and nausea and vomiting.
Hyperosmia: Symptoms, causes, and treatment
Migraines are a type of headache that can cause recurrent attacks of moderate to severe pain. The reason why some people have migraines is currently unknown, but environmental changes, such as the weather, can trigger a migraine. Environmental triggers can also include certain smells. As a result, people with hyperosmia may be more likely to experience migraines when they smell particular odors.

In some cases, hyperosmia may lead to depression or anxiety. Causes A pregnant woman may experience hyperosma because of hormonal changes. There may be a genetic reason that makes some people more likely to develop hyperosmia than others. Scientists need to carry out more research to fully understand this possible genetic link and to develop potential treatments.

Hyperosmia typically occurs alongside another condition. Complications and associated conditions Hyperosmia is sometimes caused by migraines.
One study found that between 25 to 50 percent of the 50 patients in their study experienced some version of hyperosmia during their migraine attacks. This can be isolating because it may be difficult for you to attend certain events or go to certain places.
Causes Hyperosmia is associated with multiple conditions and can trigger a variety of symptoms. Some conditions associated with hyperosmia can cause the change in smell, and vice versa. Because of this, it may be difficult for you to determine whether your hyperosmia is a symptom of a larger disorder or the cause of it.
Pregnancy One of the most common causes of hyperosmia is pregnancy.
An early symptom of pregnancy is a heightened sense of smell. This can trigger headaches, nausea, and vomiting during first-trimester morning sickness.
