7/6/2011

Hallucinations Hallucinations can affect all senses: Sensory perceptions that occur in the absence of any real stimulus but appear to be the result of faulty messages in the brain. Hearing (auditory) Seeing (visual) Touch (tactile) Smell (olfactory) Taste (gustatory) Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Delusions Fixed beliefs created by illness which are held y by y the pperson experiencing p g the psychosis. py only These can include: Belief in special abilities of self or others Belief that physical health is changed Belief that unusual coincidences have a special importance Belief that one is being controlled Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Thought Disorder Problems organizing thoughts. Thoughts coming to fast or too slow. Problems thinking and therefore speaking logically. Problems keeping on topic. Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Disorganized or Bizarre Behaviour: Everyone’ss behaviour is a response to how they Everyone interpret what is going on around them. People with psychosis may behave differently than they usually do. may become extremely active or agitated, may laugh l h inappropriately i i l or display di l inappropriate i i appearance, hygiene or conduct. may behave in ways that reflect their thoughts Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Negative symptoms refer to behaviours or experiences that have been reduced or lost because of the illness.

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Negative symptoms may include: Problems getting motivated Problems taking joy in things Problems getting words out Seeming flat and blunted

Cognitive Symptoms Refers to problems with learning and concentration Find it difficult to focus and pay attention find it hard to filter out all the various stimuli in their environment. (may be highly sensitive to sounds, lights and even the regular activities occurring in their immediate environment.) Easily distracted Trouble with working memory Classroom/Tim’s example

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Cognitive Symptoms find the ability and speed in processing information and reaction time may be slowed experience difficulties with memory, problem solving ability and judgement. g find it hard to organize activities in their lives,, for example to manage the time and tasks needed to get their schoolwork completed.

Mood Symptoms The person can be:

Anxious, irritable Depression Anger and unpleasant behaviour Rapid changes in mood Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Key Point Sometimes people with psychosis cannot recognize that they are ill and believe that nothing is wrong with them. This lack of insight can make it hard to get the person to accept treatment. treatment

• Common among prison and homeless populations

• 80% will abuse substances during their lifetime

•More hospital beds in Canada are occupied (8%) by people with schizophrenia than by sufferers of any other medical condition

• 15 15--25x more likely to die from a suicide attempt than the general population • 10% or patients die from

“Youth’s Greatest Disabler”

suicide most often in the first 10 years after diagnosis

World Health Report 2001 (WHO, 2002) schizophrenia and other forms of psychoses affecting young people rank third worldwide as the most disabling condition

If left untreated, there is a continuing slow increase in impairment for years

Epidemiology Schizophrenia causes massive human and financial costs Affects more than 1% of the world’s population Affects all races, ethnicities, cultures equally More severe presentation in men Allow for a more broader definition of psychotic disorder (include psychosis NOS, brief episodes, delusional disorder) lifetime rate increases to 2-3%

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Patients with schizophrenia itself die 12-15 years earlier before the average population – some quote up to 25 years earlier Schizophrenia causes more lives lost than cancer and physical illness Mostly due to poor medical care, suicide and deteriorating physical illness

Dopamine in Brain Function Dopamine is important in three areas of b i function: f ti brain Mesolimbic-frontal cortex circuits ( psychotic symptoms).

Basal ganglia (control of muscle movement). Parkinson’s disease; loss of dopamine cells

Hypothalamus-Pituitary (control of the hormone, prolactin).

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Dopamine Pathways

Four pathways:

1. 2. 3. 4.

Nigrostriatal Mesolimbic Mesocortical Tuberoinfundibular

Duration of Untreated Psychosis (DUP) Historically youth experience long DUP before coming into contact with psychiatric services 2 5 years 2-5 Long DUPS translate to very poor clinical and social outcomes We now know that if this illness is caught early, prognosis can be very positive with effective treatment

Rational Therapy for Psychotic Disorder Antipsychotic medication along with therapy/education are the cornerstone of effective treatment programs when dealing with a known chronic psychotic illness such as schizophrenia

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Antipsychotic Medications All antipsychotic medications influence communication between brain cells involving the neurotransmitter, dopamine. Each medication may also influence a number of other neurotransmitters in the brain, but the effect on dopamine seems to be one common factor in reducing psychosis.

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

7/6/2011

First and Second Generation Antipsychotics “Traditional” or “First Generation” antipsychotic medications (1950-1988) (dopamine blockade): Haloperidol, Chlorpromazine, Thioridazine and many others.

Second Generation antipsychotics (serotonin-dopamine antagonism) “Clozapine / Clozaril (1990) Risperidone / Risperdal (1992) p / Zyprexa yp ((1996)) Olanzapine Quetiapine / Seroquel (1998) Ziprasidone / Zeldox (2008) Paliperidone / Invega (2008) Aripiprazole (Abilify, 2009) Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Side Effects First generation (due to Dopamine receptor blockade): Extrapyramidal (movement) symptoms (EPS) Muscle stiffness, restlessness, involuntary movements. The use of anti-parkinsonian “side effect” meds. Prolactin (hormonal) elevation. y Ammenorhea and sexual dysfunction “Dysphoria” (feeling bad). Difficulty with concentration and memory.

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

26


7/6/2011

Side Effects Second generation antipsychotics: Sedation (early in treatment) d f i Sexuall dysfunction Weight gain Metabolic dysregulation Dylipidemia Hypertriglyceridemia Risk for diabetes Cardiac dysfunction Glaucoma Stroke

Extrapyramidal side effects still a concern

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

General Treatment Guidelines Individual basis Try to treat with one medication at a time. If there is an insufficient clinical improvement after 3-6 months, try a different medication. Use continuous treatment with medication for as long as possible.

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

27


7/6/2011

Treatment: How Long? Current guidelines suggest that patients should continue on medication for at least two years after remission (no evidence of any ongoing symptoms) After 2 years studies show that about 20% may be able to come off of the medication and stay well Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Treatment: How Long? 50% of patients who do not take medication in the first year will relapse 40-60% with effective treatment (medicine, therapy, education, rehabilitation) can lead productive lives achieving life goals had prior to the onset of illness

Key Points Psychosis is treatable. Medication is a necessary, but not sufficient, part of a total treatment plan. The stress-vulnerability model helps us understand treatment. Adherence with treatment, including medications, is a critical issue. Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Challenges to Treatment Non-adherence Non adherence Depression/risk of suicide Substance use/abuse Excessive stress/expectations Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

29


7/6/2011

Definition of Non-Adherence Non-adherence (or non-compliance) means not following the recommended treatment, possibly including a refusal to take medication Taking less than prescribed Taking T ki medication di i erratically i ll (missing ( i i doses) d ) Completely stopping medication

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Predictors of Non-Adherence Denial of illness Symptoms of Illness Delusions Depression Cognitive impairment

Belief that medications no longer needed (I’m cured). Attitudes Attit d off family f il andd friends

Support Network Stigma Insight Distressed by side effects Drug induced dysphoria (feeling bad) or akathisia (restlessness) Cost of Medication

Depression Major depression during course of illness : 60% Post-psychotic Depression: 25% Attempted suicide: 25% - 40% Successful suicide: 10% - 13%

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Challenges: Substance Use/Abuse Substance use is very common in first i d psychosis h i episode Up to 80% Cannabis and alcohol are most frequently abused substances

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

31


7/6/2011

Cannabis and Early Psychosis People with psychotic disorders have higher rates of cannabis use than the general population Cannabis use is associated with poorer functional and clinical outcomes in this population, e.g. greater psychotic symptom severity the effects of which can last up to 4 years later Cannabis misuse associated with 4 times the risk of psychotic relapse One of the strongest predictors or risk factors associated with the onset of psychotic illness There is little evidence that the high rates if cannabis are is related to selfmedication for distressing symptoms or side effects of meds

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

Common Issues in Recovery Daily Life Lack of structure/disorganization Lack of supports required to return to school or work Negative experiences No plan to help recovery Lack of motivation

Relationships Trying to establish independence from family Loneliness/Separation from social groups Increased anxiety in social groups Difficulties in re-establishing relationships

Recovery takes time

• PACE Clinic (Personal Assessment and Crisis Evaluation) – Melbourne, AUS • PRIME Clinic (Prevention through Risk Identification, Management & Education)

– Yale University, US & Toronto, Ontario

Developed and validated criteria which can be applied to a population that is “help-seeking” (already ill to some extent) that might be timed to the onset of psychotic disorder - pick up on subsyndromal psychotic symptoms along with a recent worsening of functioning - goes beyond risk based only on genetic history - for the first time we can track the progression of schizophrenia

Using these criteria, studies have quoted the ability to predict conversion to psychotic disorder in 11-35% - higher than the general population prevalence of schizophrenia of 1%

Academy in School Mental Health Presented by: Sun Life Financial Chair in Adolescent Mental Health

“It It is not an easy task to recognize psychosis in the early stages and motivate a young psychotic person, who might have persecutory delusions or other delusional beliefs, to accept psychiatric treatment.”

7/6/2011

Challenges in identifying the prepsychotic phase The earliest symptoms identified are non-specific: Sleepp disturbance Depressed mood Anxiety

behavioral disturbance social withdrawal irritability

In youth, changes that occur as part of the normal developmental continuum can complicate psychiatric diagnoses. Patient age, gender, developmental stage, identity, culture, belief system are all significant diagnostic and therapeutic factors The differential diagnosis for psychosis is widespread in youth and depends upon a number of environmental factors that must be examined 40% cases – initial diagnosis has cause to be changed in 3 months
