Delusion vs. Hallucination

Hallucinations are false or distorted sensory experiences that appear to be veridical perceptions. These sensory impressions are generated by the mind rather than by any external stimuli, and may be seen, heard, felt, and even smelled or tasted.

A delusion is a false belief based on incorrect inference about external reality that is firmly sustained despite what almost everybody else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary. The belief is not one ordinarily accepted by other members of the person's culture or subculture (e.g., it is not an article of religious faith).

A hallucination occurs when environmental, emotional, or physical factors such as stress, medication, extreme fatigue, or mental illness cause the mechanism within the brain that helps to distinguish conscious perceptions from internal, memory-based perceptions to misfire. As a result, hallucinations occur during periods of consciousness. They can appear in the form of visions, voices or sounds, tactile feelings (known as haptic hallucinations), smells, or tastes.

Delusions are a common symptom of several mood and personality-related mental illnesses, including schizoaffective disorder, schizophrenia, shared psychotic disorder, major depressive disorder, and bipolar disorder. They are also the major feature of delusional disorder. Individuals with delusional disorder suffer from long-term, complex delusions that fall into one of six categories: persecutory, grandiose, jealousy, erotomanic, somatic, or mixed.

Introduction (from Wikipedia) A delusion is commonly defined as a fixed false belief and is used in everyday language to describe a belief that is either false, fanciful or derived from deception. In psychiatry, the definition is implies that the belief is pathological. A hallucination is a perception in the absence of a stimulus. In a stricter sense, hallucinations are defined as perceptions in a conscious and awake state in the absence of external stimuli which have qualities of real perception.

edit Hallucinations

In many cases, chronic hallucinations caused by schizophrenia or some other mental illness can be controlled by medication. If hallucinations persist, psychosocial therapy can be helpful in teaching the patient the coping skills to deal with them. Hallucinations due to sleep deprivation or extreme stress generally stop after the cause is removed.

edit Delusions

Delusional disorder is typically a chronic condition, but with appropriate treatment, a remission of delusional symptoms occurs in up to 50% of patients. However, because of their strong belief in the reality of their delusions and a lack of insight into their condition, individuals with this disorder may never seek treatment, or may be resistant to exploring their condition in psychotherapy.

I have been questioning my state of mind, concerned it could be delusions. I am 52 yrs
old postmenopausal w/fracture of my own thyroid remaining. Never took HRT, blood always ok for past 23+ years. I've always had a lot of thoughts of, "fear", "doubt" and "worry", most of my life. Has worsened over years, and it has come back to my attention that something my be wrong. I requested my GYN put me on HRT as my moods and thoughts in the last few months have been bad. She put me on Combipatch, seems to help although I still find myself having random thoughts of fear, worry, doubt, just not as bad as before. I also take 20 mg day of prozac, have to over 20 yrs. and now Xnax .25 mg as needed. I am adopted, don't know anyting about birth parents geneics. I am very concerned about myself as I'm getting older, should I be?

Thank you for your comments - "Fearful", "Worried", Doubtful" & TIRED

To the one who is fearful, worried and tired, this is not a mental illness but a spiritual battle which has been won for you by Jesus Christ. All you have to do is believe in Him and give Him your burdens. He said lay all your burdens down because His burden is light. Call out to Him with sincerely and He will answer! I know because I was there once!? You are in my prayers.
