    The word "hallucination" comes from Latin and means "to wander mentally." Hallucinations are defined as the "perception of a nonexistent object or event" and "sensory experiences that are not caused by stimulation of the relevant sensory organs." In layman's terms, hallucinations involve hearing, seeing, feeling, smelling, or even tasting things that are not real. Auditory hallucinations, which involve hearing voices or other sounds that have no physical source, are the most common type. Hallucinations occur frequently in people with psychiatric conditions, including schizophrenia and bipolar disorder, however, you don’t necessarily need to have a mental illness to experience hallucinations.

    There are five types of hallucinations, including:1 1. Auditory: Hearing voices or sounds that no one else can (most common type of hallucination) 2. Visual: Seeing people, colors, shapes, or items that aren't real (second most common type of hallucination) 3. Tactile: Feeling sensations (like bugs crawling under your skin) or as if you're being touched when you're not 4. Olfactory: Smelling something that has no physical source (less common than visual and auditory hallucinations) 5. Gustatory: Having a taste in your mouth that has no source (rarest type of hallucination)

    Hallucinations can have a range of symptoms, depending on the type, including: 1. Feeling sensations in the body (such as a crawling feeling on the skin or movement) 2. Hearing sounds (such as music, footsteps, or banging of doors) 3. Hearing voices (can include positive or negative voices, such as a voice commanding you to harm yourself or others) 4. Seeing objects, beings, or patterns or lights 5. Smelling an odor (can be pleasant or foul and in one or both nostrils) 6. Tasting something (often a metallic taste)

    After asking about your symptoms, medical history, and lifestyle habits, your health provider will likely do a physical exam and order a few tests to try and rule out medical or neurological causes of your hallucinations. Diagnostic tests may include: 1. Blood tests to check for metabolic or toxic causes 2. Electroencephalogram (EEG) to check for abnormal electrical activity in your brain and to check for seizures 3. Magnetic resonance imaging (MRI) to look for structural brain issues such as a brain tumor or stroke

    Hallucinations are most often associated with schizophrenia, a mental illness characterized by disordered thoughts and behaviors. However, they are also a possible characteristic of bipolar disorder. With bipolar I disorder, hallucinations are possible both with mania and depression. In bipolar II, hallucinations may occur only during the depressive phase. Bipolar disorder that presents with hallucinations and/or delusions can also lead to a diagnosis of bipolar disorder with psychotic features.3 Not only do hallucinations occur with mental health conditions like schizophrenia and bipolar disorder, but they can also occur with the following physical and psychological conditions as well:4 1. Alcohol or drug use and/or withdrawal 2. Auditory nerve disease 3. Dissociative identity disorder (DID) 4. Epilepsy 5. Glaucoma 6. Hallucinogen use 7. Metabolic conditions 8. Middle or inner ear diseases 9. Migraine 10. Narcolepsy 11. Neurologic disorders 12. Ophthalmic diseases 13. Post-traumati...

    The treatment of hallucinations will depend on the type of hallucination, the underlying cause, and your overall health. In general, however, your doctor will likely recommend a multidisciplinary approach that includes medication, therapy, and social support.

    An important aspect of helping a loved one who is experiencing hallucinations is reassuring them that treatment is available. Here are a few more practical steps for helping your loved one cope with hallucinations.
