Drug addiction is a complex condition characterized by intense and, at times, uncontrollable drug craving, along with the desire to compulsively seek and use drugs that persists even in the face of devastating consequences. While the path to drug addiction begins with the voluntary act of taking drugs, over time, the ability of a person to choose not to do so becomes compromised and seeking and consuming the drug becomes compulsive. This behavior results largely from the effects of prolonged drug exposure on brain functioning. Addiction is a brain disease that affects multiple brain circuits, including those involved in reward and motivation, learning and memory and inhibitory control over behavior. Some individuals are more susceptible to becoming an addict, depending on genetic makeup, age of exposure to drugs, other environmental influences and the interplay of all these factors. Addiction is often more than just compulsive drug consumption and can have far reaching consequences. For example, drug abuse and addiction increase the risk of a person to have a variety of other mental and physical illnesses related to a drug abuse. People may suffer the toxic effects of the drugs themselves. Additionally, a wide range of dysfunctional behaviors may result from drug abuse and interfere with normal functioning within a family, the workplace and the community. Because drug abuse and addiction have so many dimensions and disrupt so many aspects of the life of an individual, treatment is not simple. Effective treatment programs typically incorporate many components, each directed to a particular aspect of the illness and its consequences. Addiction treatment must help the individual stop using drugs, maintain a lifestyle free of drugs and achieve productive functioning in the family, at work and in society. Because addiction is typically a chronic disease, people cannot simply stop using drugs for a few days and halt addiction. Most patients require long term or repeated episodes of care to achieve the ultimate goal of sustained abstinence and recovery of quality of life. Research and clinical practices demonstrate the value of continued care in treating addiction, with researchers studying a variety of approaches in both residential and community settings. The future holds new research results on the influence of genetics and environment on gene function and expression, which will herald the development of personalized treatment interventions. Clinicians will integrate this information with current evidence that supports the most effective drug abuse and addiction treatments and implementation.

Comorbid Drug Abuse and Mental Illness

When two disorders or illnesses occur simultaneously in the same person, they are comorbid. Surveys show that drug abuse and other mental illnesses are often comorbid. Six out of ten people with a substance abuse disorder may also suffer from another form of mental illness. The high prevalence of comorbidities does not mean that one condition causes the other, even if one appears first. Drug abuse can cause a mental illness. Mental illness can lead to drug abuse. Common risk factors cause drug abuse and mental disorders.

Implants

There are many kinds of implants. The artificial pacemaker helps to regulate heart rhythms. Lithium-ion batteries may provide long-lived provision of energy to such devices. A bio-implant is a biomaterial surgically implanted to replace damaged tissue. Common areas of application include orthopedic re-constructive prosthesis, cardiac prostheses, the skin and the cornea. A breast implant alters the size and shape of the breasts. There are two primary types of breast implants: saline-filled and silicone-gel-filled implants. Saline implants have a silicone elastomer shell filled with sterile saline liquid. Silicone gel implants have a silicone shell filled with a viscous silicone gel. Dental implants are a kind of implant that exist both inside and outside the body. An oral surgeon embeds the implant in the bone of the mandible or maxilla and the top of the implant is visible from within the mouth. In orthopedic surgery, implants may refer to devices over or within bones that hold a fracture in place. Prosthesis is a more appropriate term for devices that replace a part or whole of a defunct joint. In this context, implants may be within or outside the body.
