Is Drug Addiction a pathology?

From this perspective, addiction is a pathology in mechanisms of brain neuroplasticity that are used to establish the adaptive hierarchy of behaviors that ensure survival.

What is the pathology of addiction?

Addiction can be viewed as a pathology in how importance is attached to stimuli that predict drug availability and how the brain regulates (chooses) behavioral output in response to those stimuli. Thus, end-stage addiction is characterized by the excessive motivational importance of drug seeking.

What are the 4 types of drug classifications?

The main categories are:

• stimulants (e.g. cocaine)
• depressants (e.g. alcohol)
• opium-related painkillers (e.g. heroin)
• hallucinogens (e.g. LSD)

What are the 5 classifications of drugs?

The five classes of drugs are narcotics, depressants, stimulants, hallucinogens, and anabolic steroids.

What is the reward pathway of addiction?

A reward pathway, or reward system, refers to a group of brain structures that are activated by rewarding stimuli. The most crucial reward pathway in the brain is known as the mesolimbic dopamine system. Though there are other existing reward pathways, the dopamine reward system is a key detector of rewarding stimuli.

What is the neural basis for addiction?

Results: While dopamine is critical for acute reward and initiation of addiction, end-stage addiction results primarily from cellular adaptations in anterior cingulate and orbitofrontal glutamatergic projections to the nucleus accumbens.

What does pathology mean in medical terms?

Pathology is a branch of medical science that involves the study and diagnosis of disease through the examination of surgically removed organs, tissues (biopsy samples), bodily fluids, and in some cases the whole body (autopsy).

What is substance use disorders?

Drug addiction, also called substance use disorder, is a disease that affects a person’s brain and behavior and leads to an inability to control the use of a legal or illegal drug or medication. Substances such as alcohol, marijuana and nicotine also are considered drugs.

What are the 7 drug categories?

The DRE categorization process is premised on these long-standing, medically accepted facts. DREs classify drugs in one of seven categories: central nervous system (CNS) depressants, CNS stimulants, hallucinogens, dissociative anesthetics, narcotic analgesics, inhalants, and cannabis.

What are the six classification of drugs?

When considering only their chemical makeup, there are six main classifications of drugs: alcohol, opioids, benzodiazepines, cannabinoids, barbiturates, and hallucinogens. Out of all the thousands of drugs that are out there, both prescription and illegal, each one can be categorized under one of these six headings.

What are the 3 major categories of drugs?

The below sub-section summarises the major classifications of drugs including stimulants, depressants and hallucinogens.

Which is the leading cause of death from drug abuse?

The abuse of alcohol contributes to many deaths per year worldwide. One of the most common drug overdoses leading to death is ingestion of a large amount of alcohol. A product known as “powdered alcohol” has become available in some locations.

What kind of virus is associated with drug reaction?

Drug reaction with eosinophilia and systemic symptoms (DRESS) is associated with reactivation of inactive Herpesviridae family viruses, including human herpesvirus 6 (HHV6), Epstein-Barr virus (EBV) and cytomegalovirus (CMV) ( Arch Dermatol 2001;137:301, Br J Dermatol 2006;155:344, Arch Dermatol 2009;145:1030 )

How are drug molecules related to the immune response?

Drug molecules causing an immune reaction are proposed mechanisms of pathogenesis of drug hypersensitivity, including hapten theory (drug molecules bind to a protein and cause antigenicity), p-i concept (drug molecules bind to HLA and cause T cell response) and drug molecules interacting with certain HLA subtypes.

How are hematologic in vitro and drug provocation tests unreliable?

Hematologic, in vitro, and drug provocation tests are either unreliable or impractical. Methods: This was a descriptive, prospective study to assess and compare histopathological features of maculopapular viral and drug exanthem. Subjects fulfilling case definition of exanthems were included.
