What causes illusions, delusions, and hallucinations?

What causes illusions, delusions, and hallucinations?

Illusions are simple: Perceptual distortions, seeing things that aren't there because of low lighting, atmospheric distortion, etc. Once light is shined on the cause, the illusion disappears.

Please tell me exercises that can help create definition around the waist, and an illusion of curves on a very slender frame?

Please tell me exercises that can help create definition around the waist, and an illusion of curves on a very slender frame?

Cardio Mix: You can not target specific areas for weight loss - if you have adipose tissue to lose (not everyone does), then consider an increase in cardio and a balanced diet. However, do not always do the same exercise or you will increase your risks for stress injuries. Mix things up with walking, running, biking, swimming, or circuit training. Ultimately you need to burn more than you consume. ...Read more

To get the figure you desire is a function of your heredity, exercise program (try a gym with advice available), and diet. A carefully designed program can get you looking your best but perhaps not like the artificial kim k. ...Read more

How does caffeine affect cognition? Does it actually speed up thought or simply create an illusion that it enhances/speeds up thought?

How does caffeine affect cognition? Does it actually speed up thought or simply create an illusion that it enhances/speeds up thought?

Caffeine: Caffeine can speed up thinking processes a bit, and improve declarative memory (such as memorizing lists). But it doesn't help when it comes to creative energy -- thinking beyond basic tasks. Caffeine only increases the output and quality of your work if the work you're doing doesn't require nuanced or abstract thinking. In the process it makes you more vulnerable to stress. Hmmmm. . ...Read more

M 11-12 weeks pregnant n I m feeling baby movement since last 3 days early morning is this the movement or it just my illusion?

Probably imagination: Feeling the baby move usually occurs at 16-18 weeks. This is called quickening.

Test your migraine if you have another and you can find the source which is probably the occipital lobe in the brain. ...Read more

Is illness illusion the same of obsessive compulsive? The idea of being ill by heart attack is settled in my mind. I can't get rid of it. Thanks

"Illness illusion": Some people with ocd focus on their health, becoming anxious about dire illnesses or contaminations -- but these are not the only obsessive thoughts they have. Others have high health anxiety but no other obsessions -- they might have somatoform disorders. So, "illness illusion" is not exactly the same as ocd. There is help for both conditions with cognitive behavioral therapy, though. ...Read more
