addiction treatment
No matter what stage an addict is at, if there is breath, there is hope. As a society, we have come a long way in treating addiction and mental health issues as a whole. With treatment centers and programs like the Watershed, offered all over the United States, there is help out there and we do recover.
DRUG ABUSE/CATEGORIES OF DRUGS/ NARCOTICS/PREVENTION OF DRUG ADDICTIONWasim Ak
DRUG ABUSE OR SUBSTANCE ABUSE REFERS TO THE USE OF CERTAIN CHEMICALS FOR THE PURPOSE OF CREATING PLEASURABLE EFFECTS ON THE BRAIN. THERE ARE OVER 190 MILLION DRUG USERS AROUND THE WORLD AND THE PROBLEM HAS BEEN INCREASING AT ALARMING RATES, ESPECIALLY AMONG YOUNG ADULTS UNDER THE AGE OF 30.
A DRUG IS A CHEMICAL THAT INTERACTS WITH PROTEINS IN THE BODY TO AFFECT A PHYSIOLOGICAL FUNCTION. THIS IS THE GENERAL IDEA BEHIND ALL MEDICINE. ONCE THESE CHEMICALS ARE ABSORBED INTO THE SYSTEMIC CIRCULATION THEY BIND WITH CERTAIN PROTEINS AND THIS CHANGES THE FUNCTIONING OF THE CELL SLIGHTLY.
A DRUG IS ANY SUBSTANCE THAT , WHEN ABSORBED INTO THE BODY OF LIVING ORGANISM , ALTERS NORMAL BODILY FUNCTIONS . DRUGS ARE CHEMICALS THAT CHANGE THE WAY A PERSON’S BODY WORKS BY ALTERING EMOTIONS AND THOUGHTS .
DRUG ABUSE MAY BE DEFINED AS THE HABITUAL USE OF DRUGS NOT NEEDED FOR THERAPEUTIC PURPOSES, SOLELY TO ALTER ONE’S MOOD, AFFECT, STATE OF CONSCIOUSNESS, OR TO AFFECT A BODY FUNCTION UNNECESSARILY.

This presentation focuses on habits we can fix that will reduce our levels of stress. It also goes into depth about what supplements our body should be consuming.
The Biopsychosocial model was first conceptualised by George Engel in 1977, suggesting that to understand a person's medical condition it is not simply the biological factors to consider, but also the psychological and social factors.
The “biopsychosocial (BPS) model” emphasizes the interconnection between biological, psychological and socio-environmental factors. When this model is applied to health, it demonstrates the importance of maintaining wellness in all aspects of our lives.
The biopsychosocial model is an inter-disciplinary model that looks at the interconnection between biology, psychology, and socio-environmental factors. The model specifically examines how these aspects play a role in topics ranging from health and disease, to human development.
As well as being able to explain mental health in terms beyond the purely biomedical, it shows us there is potential to positively influence a person's mental health in the workplace.
Why it is important for mental well-being. The biopsychosocial model encourages clinicians to explain phenomena such as depression by examining all relevant biological, psychological, and social factors that might be contributing to the development or maintenance of the disorder.
The biopsychosocial model has been described both as a philosophy of clinical care and a guide for clinical practice [1]. It proposes that suffering, disease, or illness involve a host of factors from biological (tissues, structures, molecules) to environmental (social, psychological).The biopsychosocial model is an inter-disciplinary model that looks at the interconnection between biology, psychology, and socio-environmental factors. The model specifically examines how these aspects play a role in topics ranging from health and disease, to human development. The biopsychosocial model is a general model positing that biological, psychological (which includes thoughts, emotions, and behaviors), and social (e.g., socioeconomically, socioenvironmental, and cultural) factors, all play a significant role in health and disease.Which factors influence health, according to the biopsychosocial model? b. The biopsychosocial model suggests that health and illness are determined by psychological, biological, and social factors.Biopsychosocial model helps primary care doctors to understand interactions among biological and psychosocial components of illnesses to improve the dyadic relationship between clinicians and their patients and multidisciplinary approaches in patient care.
- The biopsychosocial approach to mental health looks at the way both internal and external factors influence our mental state. - This model acknowledges that we should look at the 'whole' patient and all of their circumstances when trying to support and understand their mental health.

Despite the high frequency of spinal related pain disorders, few patients or physicians understand or even acknowledge the role nutrition plays in pain perception. This presentation will explain the anatomy of the most common spinal structures responsible for being sources of pain. The lecture will also examine the robust role diet plays in increasing or decreasing the perception of pain.

العلاج من الادمان على المخدرات - علاج ادمان المخدرات المراحل والاسباب والعلاج
الادمان على المخدرات حالة من الهروب المعبِّرة عن سوء التوافق والدالة على وجود اضطراب في الفردية مما يتطلب تدخلا نفسيا ممتدا لنتمكن من إعادة بناء الفردية ؛ حيث تشير الدراسات أن المدمنين يعانون اضطرابا ونقصا في الصحة النفسية .
يبدأ علاج ادمان المخدرات في اللحظة التي يقرر فيها الشخص التوقف عن تعاطي المخدرات. ومن الأهمية بمكان أن يكون هو الذي اتخذ القرار بالتوقف ولم يفرض عليه وإلا فإنه لن يلبث أن يعود إلى التعاطي في أول فرصة…

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The

5. DSM-IV CRITERIA FOR SUBSTANCE DEPENDENCE
• TOLERANCE
• WITHDRAWAL
• SUBSTANCE TAKEN IN LARGER AMOUNTS OR OVER A LONGER PERIOD THAN INTENDED
• PERSISTENT DESIRE OR UNSUCCESSFUL EFFORTS TO CUT DOWN OR CONTROL SUBSTANCE USE
• GREAT DEAL OF TIME SPENT IN ACTIVITIES NECESSARY TO OBTAIN SUBSTANCE, USE SUBSTANCE
(E.G., CHAIN SMOKING), OR RECOVER FROM EFFECTS
• IMPORTANT SOCIAL, OCCUPATIONAL, OR RECREATIONAL ACTIVITIES GIVEN UP OR REDUCED

6. PHYSICAL VS. PSYCHOLOGICAL DEPENDENCE
• PHYSICAL DEPENDENCE
• WITHDRAWAL SYMPTOMS IN THE ABSENCE OF THE DRUG
• TOLERANCE TO ITS EFFECTS WITH REPEATED USE
• PSYCHOLOGICAL DEPENDENCE
• “A RELATIVELY EXTREME, PATHOLOGICAL STATE IN WHICH OBTAINING,
TAKING, AND RECOVERING FROM A DRUG REPRESENTS A LOSS OF
BEHAVIORAL CONTROL OVER DRUG TAKING WHICH OCCURS AT THE
EXPENSE OF MOST OTHER ACTIVITIES AND DESPITE ADVERSE
CONSEQUENCES” (ALTMAN ET AL)
• “A SITUATION WHERE DRUG PROCUREMENT AND ADMINISTRATION APPEAR
TO GOVERN THE ORGANISM’S BEHAVIOR, AND WHERE THE DRUG SEEMS TO
DOMINATE THE ORGANISM’S MOTIVATIONAL HIERARCHY” (BOZARTH)
7. CLASSIC MODELS OF ADDICTION

Moral Personal responsibility; self-
control
Moral suasion; social/legal
sanctions

Social policy; social services
9. PHYSICAL DEPENDENCE OR WITHDRAWAL MODEL
(NEGATIVE REINFORCEMENT)
• SOME DRUGS PRODUCE PHYSICAL DEPENDENCE AND WITHDRAWAL
SYMPTOMS UPON CESSATION OF DRUG-TAKING.
• WITHDRAWAL SYMPTOMS ARE PRODUCED BY THE BODY IN ORDER TO
COMPENSATE FOR THE UNUSUAL EFFECTS OF THE DRUG.
• WITHDRAWAL SYMPTOMS ARE GENERALLY THE OPPOSITE OF THE EFFECT
PRODUCED BY THE DRUG.
• ADDICTS CONTINUE TO USE DRUGS IN ORDER TO AVOID
WITHDRAWAL.
• OVER TIME, DRUGS NO LONGER HAVE THE SAME REWARDING
EFFECTS - THEY MERELY ALLOW THE PERSON TO FEEL “NORMAL.”
10. INADEQUACIES OF WITHDRAWAL MODEL
• NOT ALL ABUSED DRUGS GENERATE WITHDRAWAL SYMPTOMS (COCAINE,
AMPHETAMINE).
• DIFFERENT DRUGS PRODUCE DIFFERENT WITHDRAWAL SYMPTOMS WITH
DIFFERENT NEURAL BASES.
• ONCE DEPENDENT YOU SHOULD CONTINUE TAKING DRUG, BUT PEOPLE
SPONTANEOUSLY STOP.
• ONCE DRUG-ABSTINENT, USERS SHOULD NOT RELAPSE SINCE MOTIVATION
HAS DISAPPEARED, BUT THEY DO.
• NO EXPLANATION AS TO WHY PEOPLE TAKE DRUGS IN THE FIRST PLACE.
11. POSITIVE INCENTIVE (HEDONIC) MODELS
(POSITIVE REINFORCEMENT)
• DRUGS PRODUCE PLEASURE - A “HIGH.”
• SOME DRUGS PROVIDE INDIRECT POSITIVE INCENTIVE - THEY
DISINHIBIT BEHAVIOR THAT IS NORMALLY SUPPRESSED (E.G., ALCOHOL
AND SOCIAL SKILLS).
• MOST DRUGS OF ABUSE STIMULATE THE BRAIN’S REWARD CIRCUITS.
• ALL KNOWN DRUGS OF ABUSE STIMULATE RELEASE OF
DA/OPIOIDS IN THE NUCLEUS ACCUMBENCY
• ANIMALS WILL WORK TO MICRO-INJECT DRUGS OF ABUSE AND
ELECTRICALLY STIMULATE THE SAME PARTS OF THE BRAIN
• NORMAL REWARDS (FOOD, DRINK, SEX) ALSO STIMULATE DA
RELEASE
12. ANIMAL MODELS OF REINFORCEMENT (CONT.)
• SELF-ADMINISTRATION
• ANIMALS WORK FOR REINFORCING
DRUGS (IV, ORAL, INHALANT)
• SCHEDULES OF REINFORCEMENT
(FIXED, PROGRESSIVE RATIO)
16. OPPONENT PROCESS MODEL
(SOLOMON, 1977)
• DRUG-USE INITIALLY MOTIVATED BY POSITIVE REINFORCEMENT
• OVER TIME, TOLERANCE TO REWARDING EFFECTS, BUT ABSTINENCE LEADS TO
WITHDRAWAL
• DRUG USE ULTIMATELY MAINTAINED BY NEGATIVE REINFORCEMENT
17. CURRENT TRADITIONAL VIEW
(BASED ON OPPONENT PROCESS MODEL)
• INITIATION OF DRUG TAKING IS PRIMARILY DRIVEN BY ANTICIPATED PLEASURE
(FACILITATED BY PEER PRESSURE, SOCIAL FACILITATION, CURIOSITY).
• FOR MOST DRUGS, PLEASURE BECOMES PRIMARY MOTIVATOR AND DRUG CRAVING
BECOMES CUED BY DRUG RELATED STIMULI.
• FOR SOME DRUGS (E.G., ALCOHOL, COCAINE, HEROIN) PLEASURE IS ENHANCED BY
REVERSING UNPLEASANT ASPECTS OF NORMAL LIFE.
• FOR SOME DRUGS (E.G., NICOTINE, CAFFEINE, HEROIN, ALCOHOL), DRUG-TAKING
LEADS TO DEPENDENCE AND WITHDRAWAL WHICH ADDS ADDITIONAL MOTIVATION TO
CONTINUE DRUG-TAKING HABIT AND MAKES “GIVING UP” DIFFICULT.
• THIS WITHDRAWAL STATE CAN ALSO BE ASSOCIATED WITH ENVIRONMENTAL CUES,
AND INCREASES THE TENDENCY FOR RELAPSE.
18. LIMITATIONS OF OPPONENT PROCESS
MODELS
• DRUG WITHDRAWAL IS MUCH LESS POWERFUL AT MOTIVATING
DRUG-TAKING BEHAVIOR
• STRESS SEEMS TO BE MORE POWERFUL
• WITHDRAWAL SYMPTOMS ARE MAXIMAL WITHIN A FEW DAYS AFTER
CESSATION OF DRUG USE, BUT SUSCEPTIBILITY TO RELAPSE
CONTINUES TO GROW FOR WEEKS TO MONTHS.
• CUES TYPICALLY FAIL TO ELICIT CONDITIONED-WITHDRAWAL.
• CRAVING IS DIFFERENT FROM WITHDRAWAL.
19. ABERRANT LEARNING
(BEYOND PLEASURE AND PAIN)
• CUES THAT PREDICT THE AVAILABILITY OF REWARDS CAN
POWERFULLY ACTIVATE DA CIRCUITRY IN BOTH ANIMALS AND
HUMANS (SCHULTZ, 1998), SOMETIMES EVEN BETTER THAN THE
REWARD ITSELF.
• THEREFORE, THE TRANSITION TO ADDICTION RESULTS FROM THE
ABILITY OF DRUGS TO PROMOTE THIS TYPE OF ABERRANT LEARNING.
20. MONKEY VTA STUDY (SCHULTZ ET AL, 1990S)
• MONKEYS CLASSICALLY-CONDITIONED
TO ASSOCIATE LIGHT WITH FOOD
• AFTER LEARNING, VTA NEURONS
INCREASE FIRING TO LIGHT INSTEAD OF
FOOD
• DECREASED FIRING IF LIGHT-CUED FOOD
DOESN’T APPEAR
• BASELINE DA = EXPECTED REWARD
• INCREASED FIRING = BETTER THAN
EXPECTED
• REDUCED FIRING = WORSE THAN
EXPECTED
21. PROBLEMS WITH ABERRANT LEARNING MODELS
• MOST HAVE FOCUSED AT THE LEVEL OF NEURONAL SYSTEMS
• FEW HAVE PROVIDED A PSYCHOLOGICAL STEP-BY-STEP ACCOUNT OF
HOW ABERRANT LEARNING COULD ACTUALLY PRODUCE ADDICTION.
• ARE THE ASSOCIATIONS S-S OR S-R LEARNING? ARE THEY EXPLICIT
OR IMPLICIT?
22. IMPLICIT LEARNING (TIFFANY, 1990)
• DRUG-TAKING HABITS ARE CAUSED BY ABERRANT LEARNING, BECAUSE
DRUGS SUBVERT NEURONAL MECHANISMS INVOLVED IN IMPLICIT
LEARNING (UNCONSCIOUS S-R OR S-S PROCESSES). URGES AND
CRAVINGS ARE OF SECONDARY IMPORTANCE TO FORCE OF HABIT
(AUTOMATICITY).
• “…WITH SUFFICIENT PRACTICE, PERFORMANCE ON ANY TASK CAN
BECOME AUTOMATIC…” AND “DRUG-USE BEHAVIOR IN THE ADDICT
REPRESENT ONE SUCH ACTIVITY, CONTROLLED LARGELY BY AUTOMATIC
PROCESSES”
• OVER-LEARNED HABITS BECOME SO AUTOMATIC THAT THEY
ESSENTIALLY BECOME COMPULSIVE
23. PROBLEMS WITH AUTOMATICITY MODELS
• THEY MISTAKE AUTOMATIC PERFORMANCE FOR MOTIVATIONAL
COMPULSION.
• HABITS (BRUSHING TEETH, DRIVING) ARE NOT INTRINSICALLY
COMPULSIVE, NO MATTER HOW AUTOMATIC THEY ARE
• WOULD YOU SACRIFICE YOUR HOME, YOUR JOB, YOUR FRIENDS TO
ENGAGE IN TEETH BRUSHING BEHAVIOR?
• MANY ASPECTS OF ADDICTIVE DRUG PURSUIT ARE FLEXIBLE AND NOT
HABITUAL
24. INCENTIVE –SENSITIZATION MODEL
(ROBINSON AND BERRIDGE, 1993)
• ADDICTIVE DRUGS PRODUCE LONG-LASTING CHANGES IN BRAIN
ORGANIZATION
• THE BRAIN SYSTEMS THAT ARE CHANGED INCLUDE THOSE NORMALLY
INVOLVED IN THE PROCESS OF INCENTIVE MOTIVATION AND
REWARD.
• ADDICTION RENDERS THESE SYSTEMS HYPERSENSITIVE (“SENSITIZED”)
TO DRUGS AND DRUG-ASSOCIATED STIMULI
• THESE SENSITIZED SYSTEMS MEDIATE A COMPONENT OF REWARD
TERMED INCENTIVE SALIENCE OR “WANTING” (NOT PLEASURE OR
“LIKING”).
25. INCENTIVE SENSITIZATION
• DRUG-INDUCED SENSITIZATION OF BRAIN SYSTEMS (DA) THAT
MEDIATE INCENTIVE-SALIENCE CAUSES DRUGS AND DRUG-
ASSOCIATED STIMULI TO BECOME COMPULSIVELY “WANTED”
• THE ACTIVATION OF THE SENSITIZED SYSTEM CAN OCCUR
BOTH IMPLICITLY OR EXPLICITLY
• THESE SYSTEMS CAN BE DISSOCIATED FROM NEURAL SYSTEMS
THAT MEDIATE THE HEDONIC EFFECTS OF DRUGS (OPIOIDS), I.E.,
HOW MUCH THEY ARE “LIKED” (WANTING IS NOT LIKING).
26. PSYCHOMOTOR SENSITIZATION
• MANY DRUGS PRODUCE PSYCHOMOTOR-ACTIVATING EFFECTS
• AMPHETAMINES, COCAINE, OPIATES, ALCOHOL, NICOTINE, MDMA
• THESE EFFECTS LAST FROM MONTHS TO YEARS AFTER DRUG USE IS
DISCONTINUED
• SOME INDIVIDUALS SENSITIZE READILY, WHEREAS OTHERS ARE MORE
RESISTANT (MAY EXPLAIN SUSCEPTIBILITY TO ADDICTION)
• GENES, HORMONES, STRESS HORMONES, PAST TRAUMA…?
• STRESS CAUSES SENSITIZATION AND MAY BIAS ADDICTION
• ADDICTION MAY MAKE AN INDIVIDUAL HYPERSENSITIVE TO
STRESS
27. INCENTIVE-SENSITIZATION MODEL
• ADDICTION MAY BE TRIGGERED BY DRUG CUES AS A “LEARNED”
MOTIVATIONAL RESPONSE BUT IT IS NOT A DISORDER OF ABERRANT
LEARNING PER SE
• IT IS A DISORDER OF ABERRANT INCENTIVE MOTIVATION DUE TO
DRUG INDUCED SENSITIZATION OF NEURAL SYSTEMS THAT ATTRIBUTE
SALIENCE TO PARTICULAR STIMULI.
28. COCAINE CUES STUDY (GRANT ET AL, 1996)
•PET = POSITRON EMISSION TOMOGRAPHY
•RADIOACTIVE MARKER INJECTED
•SCANNER DETECTS LIGHT WAVES FROM DECAY
29. COCAINE STUDY CONTINUED
•COCAINE ADDICTS AND
CONTROLS SHOWN COCAINE
CUES AND NEUTRAL CUES
•COCAINE CUES IN ADDICTS
ELICITED CRAVING, BRAIN

•ACTIVATION CORRELATED WITH
CRAVING IN DORSOLATERAL
PREFRONTAL CORTEX,
AMYGDALA, CEREBELLUM
30. SMOKING STROP STUDY (GROSS ET AL, 1993)
