Mechanisms by which a Psychoactive Drug May Exert Influence on Neural Processing

Psychotropic drugs can be defined as "chemical substances that affect consciousness and behavior by changing brain's chemical information system" (Schacter et al., 2012). Different kinds of medicines may influence the brain in various ways by promoting or mitigating spreading. They alter neuronal connectivity by preventing neurotransmitters from binding to post-brain synaptic neurons, inhibiting reuptake of neurotransmitters, or enhancing neurotransmitter binding and transmission I will. Neurotransmitters are "chemical transmitters that transmit signals between neurons in the body" (Cherry K, 2014).

Psychotropics affect consciousness by influencing how neurotransmitters function in the central nervous system (CNS) synapses. Some psychoactive agents are agonists that mimic the actions of neurotransmitters, others are antagonists that block the action of neurotransmitters, others block reuptake of neurotransmitters at synapses . . In some cases, the role of psychotropic drugs mimics other naturally occurring conscious state. For example, hypnotics are used to cause drowsiness and benzodiazepines are prescribed to produce a relaxed state. In other cases, psychoactive drugs are used for recreational purposes, creating a pleasant state of consciousness or helping us escape from normal consciousness.

Pharmacological procedures are performed using a variety of drugs that alter nerve activity by interfering with neurotransmission, resulting in changes in perception, mood, consciousness, cognition, and behavior. Psychotropic drugs are classified into different groups according to their pharmacological effects; stimulants that tend to cause euphoria, stimulants that cause a temporary improvement in mental or physical function, inhibitors that inhibit or reduce arousal or stimulation , And may cause hallucinations, perception Thoughts, emotions, and other substantial subjective changes to abnormalities and hallucinations

The result of the long-term use of psychoactive drugs is "Substantial and sustainable change of nerve function" by the dean of Steve Hyman, Harvard University who was former director of NIMH until recently. As quoted by the Turks. Hayman wrote that the brain starts to work "in a qualitative and quantitative way different from ordinary". After taking several weeks of psychotropic drugs, the compensatory efforts of the brain will begin to fail with side effects that reflect the mechanism. Role of drugs For example, SSRIs can cause manic episodes due to excessive serotonin. Since antipsychotics consume dopamine, they cause side effects similar to Parkinson's disease (Parkinson's disease is also depleted). With the advent of side effects, they are often treated with other medications, and many patients become a mixture of psychoactive drugs to diagnose cocktails. wait
