But hallucinations occur and interfere with normal life, you should consult your doctor to determine the cause. In this article, we will explore and dymstify the subject of hallucinations.
What is a Hallucination? According to Miriam-Webster, a hallucination is defined as a sensory perception – such as a visual image or a sound – that occurs in the absence of an actual external stimulus and usually arises from neurological disturbance.
Quick Facts About Hallucinations
- There are many known possible causes for other than dementia, including sleep disorders (narcolepsy), mental disorders (schizophrenia), grief, emotional trauma, strenuous exercise, drug or alcohol abuse, and certain medications.
- Hallucinations which are attributed to dementia may involve any one of the senses- sight, sound, taste, smell or touch.
- While you may think reassuring the patient that what they are experiencing is not real would be helpful, experts actually recommend the opposite strategy. It is better to listen to what they have to say, wthout expressing doubt about their visions being real.
- Early onset hallucinations – which begin soon after the diagnosis of dementia – are thought to be caused by lewy body formations in the brain. Lewy bodies are abnormal aggregations of protein that develop inside nerve cells.
Types of Hallucinations
Most people think hallucinations can only be visually experienced, but there are many types of episodes.
Visual: May be caused by certain medications, lack of sleep, depression, and a host of other conditions.
Olfactory: Two types of hallucinations involving the nose include Phantosmia (detecting odors that aren’t present) and Parosmia (misinterpreting odors that are present). These are often caused by sinusitis, hay fever, sinus infections, temporal lobe seizures, brain tumors, and Parkinson’s disease.<
Gustatory: Hypogeusia (reduced sensitivity to taste) and ageusia (inability to taste) may be attributed to epilepsy, sinus diseases, temporal lobe disease, and brain lesions.
Tactile/Somatic : These sensations may show up as a feeling that something is crawling under or on your skin, or phantom limb pain. These may be caused by schizophrenia, delirium tremens, alcohol abuse and recovery, and diseases associated with dementia.
Auditory: Hearing voices with no source is typically associated with psychoses, especially schizophrenia. They can also be associated with dementia.
Hallucinations and Dementia
Dementia patients may experience hallucinations of all kinds, but visual hallucinations are the most common. Beside hallucinations, individuals with dementia may also experience illusions (interpreting something other than what it is) or delusions.
When our loved one experiences hallucinations, illusions, or delusions it can be very disconcerting for their loved ones. They may not know how to react, and they may be tempted to try to correct or even argue with the dementia patient. However, mental health professionals advise that this may cause aggravation and anxiety – so unless the hallucinations are are posing a threat of danger, you should not overreact. You should record any episodes in order to discuss with their doctor.
