Behavioral disorders

INTOXICATION – transient syndrome due to recent substance ingestion that produces clinically significant psychological and physical impairment

ABUSE – maladaptive patterns of substance use that impair health

DEPENDENCE – certain physiological and psychological phenomena induced by repeated taking of a substance (strong desire, neglect to other sources of satisfaction, development of tolerance and a physical withdrawal state)

TOLERANCE – state in which, after repeated administration, a drug produces a decreased effect or increasing doses are required to produce the same effect

WITHDRAWAL – state is a group of symptoms and signs occurring when a drug is reduced in amount or withdrawn, lasting for a limited time

ESCALATION – refers to a phenomenon when a person taking so called softer drugs moves on to harder drugs

SYNDROME

SYMPTOMS OF ALCOHOL DEPENDENCE –Unable to keep a drink limit/Difficulty avoiding getting drunkSpending considerable time drinkingMissing meals/Memory lapses, blackoutsRestless without drink/Trembling after drinkingOrganizing day around drink Morning retching and vomitingSweating at night/Withdrawal fitsMorning drinking/Increased toleranceHallucinations/ frank delirium tremens

DIAGNOSTIC CRITERIA OF ALCOHOL WITHDRAWAL

Any THREE of the following :

Tremor of outstretched hands, tongue or eyelidsSweatingNausea / retching/ vomitingTachycardia or hypertensionAnxietyPsychomotor agitationHeadacheInsomniaMalaise or weaknessTransient visual, auditory or tactile hallucinations/illusionsGrandmal convulsions

TREATMENT – Raise awareness of the problemIncrease motivation to changeWithdraw alcohol (controlled drinking)Support and adviceCBT (Social skills, relapse prevention)Marital therapyMedication (Diazepam/chlormethiazole/Disulfiram or Acamprosate)

Psychological dependence Glue-sniffing – adolescents. Tolerance develops in weeks or months Intoxication characterized by euphoria, excitement, floating sensation, dizziness, slurred speech and ataxia Acute intoxication – amnesia + visual hallucinations There is risk of tissue damage including that to bone marrow, brain, liver and kidneys which can prove fatal

Derived directly from opium poppy: Morphine/Codeine Semi-synthetic Heroine / DiacetylmorphineSynthetic Methadone/Meperidine/Dihydrocodeine Uses Pain relief; suppression of cough; treatment of acute myocardial infarction and also diarrhea Effects Pleasant mood and a euphoric detachment Causes of death in narcotics addicts

Heart disease (including infective endocarditis)TuberculosisGlomerulonephritisTetanus/Malaria/Hepatitis B

Abrupt withdrawal is highly dangerous. May result in a mental disorder, similar to alcohol withdrawal, may lead to seizure & sometimes to death. Withdrawal symptoms may not appear for several days. Anxiety, restlessness, and disturbed sleep anorexia, nausea. May progress to vomiting, hypotension, pyrexia, tremulousness, major Seizures, disorientation & hallucinations.

Elevate mood, increase wakefulness, give an enhanced sense of mental and physical energy

Pleasurable stimulation & excitement potential of misuse

Cocaine, amphetamines, Synthetic (Phenmetrazine diethylpropon), Khat, Caffeine  

Effects similar to these Amphetamines

Strong Psychological dependence

Excitation,dilated pupils, tremulousness

Dizziness and sometimes convulsions

Confusion, depression, paranoid psychosis and formication

Chlordiazepoxide (Librium), Diazepam (Valium),

Lorazepam (Ativan) and Nitrazepam (Mogadon)

Cause: Sedation, anxiety relief and Muscle relaxation

Withdrawal Symptoms:Anxiety, restlessness, tachycardia and sensory disturbances

Produce strange, intense, & transcendental effects,which gives them ‘recreational’ popularity

Peyote, mescaline, ‘Magic mushroom’

LSD:lysergic acid diethyl-amide

Do not give rise to dependence in true sense, nonetheless use is intensely hazardous

Effects vary with dose, persons expectation , mood, & social setting

Exaggerates pre-existing mood: exhilaration, depression or anxiety

Increased enjoyment of aesthetic experience & distortion of time & space

Reddening of the eyes, dry mouth, irritation of respiratory treat & coughing

No definite withdrawal Syndrome

No evidence of Tolerance. No serious side effects amongst intermittent users

No evidence of teratogenecity. Not safe in first trimester

Psychosis: disagreement

PRE-COMTEMPLATION:Misuser doesn’t see the problem; others recognize it

ACTION USER:Choose necessary strategy for change

DECISION POINT:Where the decision is made to act on this issue

CONTEMPLATION:Individual weighs pros/cons. Considers change is needed

MAINTENANCE GAINS:Are maintained and consolidated

RELAPSE:Return to previous pattern of behavior

1.DETOXIFICATION

2.INSISTENCE ON ABSTINENCE

3.INVOLVEMENT OF FAMILY

4.TOXICOLOGY SCREENS (periodic urine screens are often essential in identifying relapse and noncompliance)

5.SELF-HELP GROUPS

6. SANCTIONED TREATMENT (patient forced to remain in therapy by a legal sanction e.g. drivers/professional

license)7. CONTINGENCY CONTRACTING

(This approach provides a powerful negative contingency for leaving treatment or relapsing or a positive contingency

for remaining drug free)
