Illusory palinopsia is a dysfunction of visual perception, resulting from diffuse, persistent alterations in neuronal excitability that affect physiological mechanisms of light or motion perception. Illusory palinopsia is caused by migraines, visual snow, HPPD, prescription drugs, head trauma, or may be idiopathic.
Illusory palinopsia is often worse with high stimulus intensity and contrast ratio in a dark adapted state.Multiple types of illusory palinopsia often co-exist in a patient and occur with other diffuse, persistent illusory symptoms such as halos around objects, dysmetropsia (micropsia, macropsia, pelopsia, or teleopsia), Alice in Wonderland Syndrome, visual snow, and oscillopsia.
The most prevalent research on prescription drugs with side effects of macropsia deals with zolpidem and citalopram. Zolpidem is a drug prescribed for insomnia, and although it has proven beneficial effects, there have been numerous reported cases of adverse perceptual reactions. [ 13 ]

Hallucinogen persisting perception disorder (HPPD) is a non-psychotic disorder in which a person experiences apparent lasting or persistent visual hallucinations or perceptual distortions after using drugs, [1] including but not limited to psychedelics, dissociatives, entactogens, tetrahydrocannabinol (THC), and SSRIs.
Long-term benzodiazepine use can lead to a generalised impairment of cognition, including sustained attention, verbal learning and memory and psychomotor, visuo-motor and visuo-conceptual abilities. [ 25 ] [ 26 ] Transient changes in the brain have been found using neuroimaging studies, but no brain abnormalities have been found in patients ...
Nootropics are touted as “smart drugs” meant to improve cognitive performance. But there’s a lot we still don’t know about them. Do nootropics really boost focus and memory?
