Dextroamphetamine: Mental effects
Last modified: Saturday, 30. May 2009 - 3:21 pm
Dextroamphetamine stimulates the production of the neurotransmitters dopamine and norepinephrine. Neurotransmitters are the brain chemicals responsible for transporting electrical impulses from nerve cell to nerve cell. Dopamine, the neurotransmitter associated with feelings of pleasure, triggers the euphoria that is related to dextroamphetamine use. Norepinephrine is a neurotransmitter thought to be responsible for the adrenaline-like effects of the drug.
Because it stimulates the central nervous system, dextroamphetamine fights mental fatigue. The drug can also improve mood and give users a sense of power, euphoria, and well-being. With chronic use, however, it may cause obsessive thoughts and feelings of paranoia, anxiety, hypersensitivity — and, in extreme cases, psychosis.
Amphetamine psychosis causes feelings of severe paranoia and auditory and visual hallucinations. The amphetamine addict who is psychotic typically experiences delusions of persecution, believing someone, or everyone, is “out to get” them. Because of these paranoid delusions, violence can frequently occur during amphetamine psychosis. Once the amphetamine abuser is free of the drug, psychosis fades quickly. However, symptoms such as mental confusion, memory problems, and delusional thoughts may last up to several months or longer.
