Powerful drugs like opiates, heroin, and methamphetamine lead to some of the most severe examples of life-threatening drug withdrawal symptoms. Extreme delusion and hallucinations during the withdrawal may cause a person to hurt themselves or others.
The most severe type of withdrawal syndrome is known as delirium tremens (DT). Its signs and symptoms include: extreme confusion. extreme agitation.
Well-supported scientific evidence shows that disruptions in three areas of the brain are particularly important in the onset, development, and maintenance of substance use disorders: the basal ganglia, the extended amygdala, and the prefrontal cortex.
Many addicts inherit a brain that has trouble just saying no to drugs. A study in Science finds that cocaine addicts have abnormalities in areas of the brain involved in self-control. And these abnormalities appear to predate any drug abuse.
“The brain's ability to repair or replace itself is not limited to just two areas. Instead, when an adult brain cell of the cortex is injured, it reverts (at a transcriptional level) to an embryonic cortical neuron.
Brain death: Irreversible cessation of all functions of the entire brain, including the brain stem. A person who is brain dead is dead, with no chance of revival.
As soon as a traumatic Event passes, most survivors experience a more-or-less irresistible urge to withdraw to a safe, quiet place. Survivors cycle through intense emotions, feelings, and sensations such as shock, fear, anger.

Different drugs can have neurotoxic and destructive effects on brain cells. Substances that are associated with neurological damage include but are not limited to alcohol, heroin, amphetamines, marijuana, opioids, inhalants, and cocaine. Drugs can damage brain cells through several mechanisms.
Addictions center around alterations in the brain's mesolimbic dopamine pathway, also known as the reward circuit, which begins in the ventral tegmental area (VTA) above the brain stem.
