Meth long term effects
Some studies have found that some of the brain damage caused by chronic methamphetamine use is partially reversible. Motor and verbal memory have shown to improve after extended abstinence from methamphetamine (14 months, but not six months). 1 ?Estimated Reading Time: 4 mins.

Long-term methamphetamine abuse has many negative consequences, including addiction. Addiction is a chronic, relapsing disease, characterized by compulsive drug seeking and use and accompanied by functional and molecular changes in the brain. Abusers often need to take higher doses of the drug, take it more frequently, or change how they take it in an effort to get the desired effect.
Chronic methamphetamine abusers may develop difficulty feeling any pleasure other than that provided by the drug, fueling further abuse. Withdrawal from methamphetamine occurs when a chronic abuser stops taking the drug; symptoms of withdrawal include depression, anxiety, fatigue, and an intense craving for the drug. In addition to being addicted to methamphetamine, people who use methamphetamine long term may exhibit symptoms that can include significant anxiety, confusion, insomnia, mood disturbances, and violent behavior.
These and other problems reflect significant changes in the brain caused by misuse of methamphetamine. Neuroimaging studies have demonstrated alterations in the activity of the dopamine system that are associated with reduced motor speed and impaired verbal learning. Research in primate models has found that methamphetamine alters brain structures involved in decision-making and impairs the ability to suppress habitual behaviors that have become useless or counterproductive.
The two effects were correlated, suggesting that the structural change underlies the decline in mental flexibility. Methamphetamine misuse also has been shown to have negative effects on non-neural brain cells how to make rocky road cookie pizza microglia.
These cells support brain health by defending the brain against infectious agents and removing damaged neurons.
Too much activity of the microglial cells, however, can assault healthy neurons. A study using brain imaging found more than double the levels of microglial cells in people who previously misused methamphetamine compared to people with no history of methamphetamine misuse, which could explain some of the neurotoxic effects of methamphetamine.
Some of the neurobiological effects of chronic methamphetamine misuse appear to be, at least, partially reversible.
Function in other brain regions did not recover even after 14 months of abstinence, indicating that some methamphetamine-induced changes are very long lasting. In addition to the neurological and behavioral consequences of methamphetamine misuse, long-term users also suffer physical effects, including weight loss, severe tooth decay and tooth loss "meth mouth"and skin sores. Skin sores are the result of picking and scratching the skin to get rid of insects imagined to be crawling under it.

We pride ourselves on offering the full spectrum of care that will meet — and exceed — the needs of each person we meet. The potentially irreversible structural and functional injury to the brain includes major physical, cognitive, and psychological changes. To fully understand the ways meth abuse affects the brain, we must first understand the ways in which methamphetamines produce their effects.
Meth greatly increases the release of dopamine, a neurotransmitter that is involved in the experience of pleasure, reward, and motor function, leading to the intense rush associated with methamphetamines. Meth increases levels of dopamine in the brain to levels ten times higher than the levels of dopamine released by use of cocaine or alcohol .
Additionally, meth use causes a buildup of dopamine in the brain that lasts eight to twelve hours, eight to twelve times longer than cocaine, which leads to the longer sustained high associated with methamphetamines . Long-term methamphetamine abuse leads to irreversible damage to the brain, leading to lasting impairment. Methamphetamine is so highly addictive, that the brain very quickly builds up a tolerance to the drug, which then sets up the cycle of meth abuse and dependence.
Chronic meth use causes addiction, which stops the brain from naturally releasing dopamine and causes cravings for meth, loss of control over meth use, and continuing usage despite negative consequences. Long-term meth use causes involuntary facial and body movements including tics, repetitive movements, writhing, twitching, jerking, flailing, tremors, and convulsions.
Methamphetamine abuse causes long-term impairment of the brain in ways that affect cognition. Meth abuse is associated with longstanding cognitive impairment, which impedes the ability of a chronic user to learn new information and perform simple verbal tasks. Meth damages the frontal lobe, the part of the brain responsible for judgment, impulse control, and the ability to understand the consequences of actions, which may lead a meth abuser to engage in previously unfathomable activities. By changing the structure of the brain, methamphetamine damages both short-term and long-term memory, which can lead to a user having the inability to remember whole periods of time and struggle recalling day-to-day things.
Long-term meth abuse leads to a number of changes in the brain which can lead to chronic psychological problems that range from mild annoyance to life-altering health problems. When going through withdrawal or detox from meth, many users struggle with debilitating depression and anxiety as over time, methamphetamines damage systems in the brain responsible for regulating emotions and the ability and capacity to feel pleasure.
The depression may be so severe for some meth addicts that suicide seems like the only way out. Methamphetamine abuse overstimulates the area of the brain responsible for emotional control — the amygdala — and affects the brain circuits needed to control impulsive behaviors.
The inability of meth users to regulate their behaviors combined with the high-energy state characterized by paranoia and anxiety makes methamphetamine users more apt to exhibit violence self or outwardly directed and aggression.
Additionally, as methamphetamine disrupts the inhibitory mechanism of the brain, chronic meth users may become obsessed with a single thing for many hours or engage in repetitive behaviors while high.
Even within the first few months of abuse, some meth users succumb to paranoia, a type of delusional disorder that leads to irrational behaviors, hypervigilance, and the feeling of being in constant danger.
With chronic usage, meth abusers may experience a break from reality, or psychosis, in which the person experiences visual, tactile, auditory, or visual hallucinations and delusions. Often, chronic meth users suffer from delusions of persecution, operating under the delusion that they are being watched by others or that others are out to get them. Most meth users begin to use the drug as an experiment without the idea that they may one day become an addict.
They may use without considering that the long-term effects of methamphetamine abuse impact virtually every area of their life, leading to unforeseen consequences. There is no doubt that methamphetamines can lead to serious health complications, including damage to nearly every organ system in the body. While some of these changes will dissipate after a year of sobriety, some will persist indefinitely .
