  1. Substance Misuse CAMHS Background etc Alcohol and drugs....rising evidence of neurobiological and social vulnerability, versus purely ‘behavioural and morally objectionable’ Brain circuitry and reward centres, euphoria with drugs focussed around brain areas involved in natural reward (food, sex and imbibing fluid)

  2. Substance Misuse CAMHS Background etc Tolerance (delayed and rapid) and sensitisation (cocaine seizures and psychosis) Withdrawal manifestations of established homeostatic changes in the brain caused by chronic use. Potentially lethal in alcohol and hypnotics. The use of long acting substances to manage withdrawal. Dependence. All those which cause dependence share action on reward centres. Specifically DA in the nucleus accumbens. DA crucial but also 5HT, Opioids, GABA and Glutamate

  3. Substance Misuse CAMHS 1960’s prevalence massive increase social movements etc (1975 70% of USA adolescents tried drugs by end of high school) Late 70’s downward trend. Increased appreciation of harm. 80’s and 90’s climbed again (prevention programmes waned, attention and finance focussed on terrorist threats) Cannabis, inahalants, LSD, cocaine, heroin Late 90’s all declined except one...Ecstasy Late 2000’s estasy declining and other designers and ‘legal highs’ increasing.

  4. Substance Misuse CAMHS Risk Factors (JAACAP 1997) Genetic SUD high in children of parents with Alcohol misuse. This could be direct inheritance or an association with ASPD in parents leading to conduct disorder, aggression and SUD in children

  5. Substance Misuse CAMHS Risk Factors (JAACAP 1997) Individual Difficulties with planning, attention, abstract reasoning, foresight, judgement, self monitoring and motor control. These factors seem similar to ADHD with CD to me

  6. Substance Misuse CAMHS Risk Factors (JAACAP 1997) Family Maternal depression and anxiety. High rates of parental SUD

  7. Substance Misuse CAMHS Risk Factors (JAACAP 1997) Peer relationships Less significant than previously thought in predicting drug use or misuse. Association may be because substance misusers select similar friendship groups

  8. Substance Misuse CAMHS Resilience Factors (JAACAP 1997) Intelligence Problem solving ability Social facility Positive self esteem Supportive family relationships Positive role models Affect regulation

  9. Substance Misuse CAMHS Groups particularly at risk : Young Offenders Looked After Children Young Homeless Children whose parents misuse drugs Those who truant or are excluded from school Young people involved in prostitution Teenage mothers Young People with Mental Health Problems Care Leavers Abused children Family disintegration (Health Advisory Service 1996)

  10. Substance Misuse CAMHS Co-morbidity is the rule ...... Substance Misuse Major depression 25-50% Anxiety disorders 20-30% ADHD 20-30% Conduct Disorder 50% plus Bulimia 10-20%

  11. Substance Misuse CAMHS Treatment CBT and Motivational Interviewing are the thing.

  12. Substance Misuse CAMHS ADHD significant risk factor for SM Risk higher is co-morbid Conduct Disorder Risk very high for cocaine and nicotine Stimulant Rx does not increase SM, it may protect from it

  13. Substance Misuse CAMHS Stimulants can be used Long acting stimulants best Atomoxetine little abuse potential Tricyclics and clonidine high risks and low evidence

  14. Substance Misuse CAMHS Dysthymia and major depression common Adult studies SSRI’s help in reducing depression and alcohol misuse 2 open studies of FLX in young people showed reduction in craving and frequency and severity of alcohol misuse FLX has a good safety profile even in non-abstinent adolescents with poly-drug misuse (Lohman 2002)

  15. Substance Misuse CAMHS Depression and SM RCT of FLX and CBT versus PLAC and CBT N=126. Age 13-19 with major depression and substance abuse or dependence Randomised : 20mg FLX or PLAC for 16 weeks Both 20 sessions CBT Weekly drug screens and CDRS Mean CDRS scores significantly down in both groups. More in FLX group Drug use decreased in both groups : No difference Riggs et al Univ of Colorado 1997

  16. Substance Misuse CAMHS Practical suggestions : Ideally wait 4 weeks after detoxification before medication But early treatment with SSRI’s can make a difference Use of CBT and SSRI’s may help both SM and depression Not yet enough evidence to suggest routine use of SSRIs to reduce alcohol misuse in Young People

  17. Substance Misuse CAMHS SM and PTSD Very often missed self medication common BDZ dependence is common Transfer to long acting BDZ Consider trial of SSRI or Mirtazapine In anxiety disorders and SUD, the presence of PTSD features predicts good outcome with SSRI’s Alcohol abuse not uncommon Specific PTSD treatment often required after management of SM

  18. Substance Misuse CAMHS SM and Psychosis Lithium in Bipolar and co-morbid alcohol and cannabis use : significant reduction in SM (Geller et al 1998) Open study CLOZ reduces SM in schizophrenia and comorbid SM Specific treatments for SM like Motivational Enhancement effective in Schizophrenia
