  4.

  8. “Mental Health”

  9. True or False? • “Mental health problems are common”

  10. Mental health problems are common 1 in 4 people in the UK will experience a mental health problem per year Bipolar Affective disorder (Manic Depression) affects 1-3 in 100 people withintheir lifetime Mental ill health costs the UK £70 bn per year

  11. True or False? • “Mental illnesses rarely get better, whereas physical health problems usually do”.

  12. Mental illnesses rarely get better, whereas physical health problems usually do. Diabetes and high blood pressure are incurable 1/3 of people with psychosis recover fully There is evidence for treatment for mental health problems in the same way as there is for physical illness.

  13. True or False? • “Mentally ill people can be dangerous”.

  14. Mentally ill people can be dangerous. 10% of homicide offenders have Schizophrenia …but if you have Schizophrenia your risk of committing homicide is 1 in 10 000 each year Every homicide gets reported and this feeds stigma If you have Mental Illness your risk of being murdered if 5 times higher

  15. True or False • “Psychiatrists mainly give people medication”.

  16. Working in mental health • Psychiatrist • Clinical Psychologist • General Practitioner • Educational Psychologist • Psychiatric Nurse • Social Worker • Occupational Therapist • Pharmacist • Research Scientist • Support Worker • Peer Support Worker • Psychotherapist • Play Therapist • Drama Therapist • Music therapist • Art Psychotherapist • Counsellor • Psychoanalyst

  17. True or False? • There is a lot of scientific evidence about mental illness.

  18. Anne Lingford-Hughes Anne Lingford-Hughes Professor of Addiction Biology, Imperial College, London Consultant Psychiatrist, CNWL NHS Foundation Trust Drugs and alcohol: what do they do to the brain?

  19. Drug misuse is caused by ‘lack of willpower’ and is not a disease like diabetes or cancer?

  20. What do people get from using drugs or psychoactive substances? • To feel good • pleasure / escape • energy • tranquillity • understanding/insights/meaning • To feel better • sleep • overcome feelings of anxiety or depression / hopelessness eg for social interactions

  21. Experimental Use (large numbers use drugs with no or little problems) ‘harmful use’- either to physical or mental health Addiction or Dependence : “lack of control”

  22. Addiction – 3 elements Social factors Addiction and its treatment Personal biological factors Drug factors Brain mechanisms

  23. Your Brain on Drugs?

  24. TO: defining which regions of brain and which chemical systems are important in different stages of drug use, misuse and addiction: help with prevention and treatment.

  25. Addiction is a brain disease which means you cannot do anything about it?

  26. Imaging the brain and its function

  27. Dopamine is released and taken back up by transporter. • Drugs of abuse increase dopamine levels by • blocking the transporter • increasing firing rate of dopamine neuron

  28. There is evidence that baseline activity in the dopamine system is involved in ‘liking’ stimulants. higher levels of dopamine activity: unpleasant lower levels of dopamine activity: pleasant

  29. This relationship also appears to apply to cognitive performance Increasing pleasure, reward Increasing anxiety, paranoia Dopamine activity Also modifiable by stress, childhood experiences etc

  30. This relationship also appears to apply to cognitive performance Increasing pleasure, reward So one strategy for prevention & treatment would be to modulate dopamine activity so it is around ‘optimal’ – not to block or boost everyone. Increasing anxiety, paranoia Dopamine activity Also modifiable by stress, childhood experiences etc

  31. Cannabis is the most harmful drug in adolescence?

  32. Alcohol main cause of global disability in 15-24 yr olds Males Females

  33. Development of ‘risky’ behaviour vs ‘impulse control’ during adolescence and early adulthood: the norm

  34. Brain changes during development – ‘reward drive’ areas mature early and ‘impulse controlling’ frontal lobes are last to finish maturing.Impact of drugs of abuse on developing brain: concern is that may be increasing future vulnerability to continuing drug misuse. Brain areas where volumes are smaller in young adultsthan adolescents Sowell, E.R. et al., 1999

  35. Model showing network of four brain circuits involved in drug liking and addiction:reward, motivation/drive, memory, control Adult Adolescence

  36. Thank you.Any questions?
