Week 5- Mental Health Flashcards
What is mental health
According to WHO, mental health is “a state of well- being in which every individual realises his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to her or his community.”
- a wellness rather than illness
- thoughts, feelings and behaviours
- we all have it
What is mental illness?
• Mental health problems and mental illnesses are conditions that significantly and adversely affects a person’s thoughts, feelings or behaviours
• Diagnosis is made with standardized criteria, e.g. DSM5 – Symptoms: +ve, -ve, cognitive
– Organic and nonorganic origins, drug induced
• Different types and degrees of severity
– Positive Mental wellbeing > mental health condition > mental illness
What are positive mental illness symptoms
Positive symptoms add. Can include hallucinations, delusions and repetitive movements that are hard to control.
What are negative mental illness symptoms
Negative symptoms take away. Can include the inability to show emotions, apathy, difficulties talking and withdrawing from social situations and relationships.
What are cognitive symptoms
The third group
Anything related to thinking, such as disorganised thoughts, memory problems and difficulties with focus and attention
How many Australians are experience mental illness
Aged 18-65, approx 1 in 5
What are common mental illness presentations
• Schizophrenia
• Psychosis including drug induced psychosis
• Addictions
• Suicide
• Bipolar disorder
• Major depression/anxiety
– Depression very common in men, anxiety very common in women
• PTSD
• Behavioural/emotional disorders, e.g. ADHD
• OCD
How is mental health typically managed
Medications and counselling
What is the influence of mental health on physical health outcomes
Mortality is higher in those with a mental illness
Why is mortality higher in the population with a mental illness
Higher incidence of cardiovascular disease and metabolic syndrome in people living with mental illness. Likely due to low levels of physical activity (especially moderate and vigorous) and higher levels of sedentary behaviour
What are the average sendentary time (hours per day) for depression, bipolar and schizophrenia?
Approximately:
Depression- 8.25hrs
Bipolar- 10ths
Schizophrenia- 12.25hrs
What is Australia’s biggest killer according to the APA?
Sitting in your house= sedentary time
What are the guidelines around exercise
Moderate- 150mins
Vigorous- 75mins
Strength- 2x week
What are other drivers of CVD, MS and comorbidity?
• Main= low levels of exercise/ high levels of sedentary behaviour
• Other drivers
– Symptoms of illness
– Medication side effects: anti-psychotics (especially atypical variety), sedatives (Cardiomyopathy, EPSE, falls and movement problems)
– MSK pain/somatic complaints (prevalent)
– Socioeconomic/patient factors/lifestyle behaviours (Substance use; Diet, sleep, smoking; Motivation and behaviour change)
– Not accessing/receiving appropriate treatment? Diagnostic overshadowing?
What is the sum effect
Sum effect: poor physical health outcomes as a whole for people living with mental illness, increased morbidity and mortality from preventable diseases
The physical health of those living with mental illness has traditionally received little attention
What is the simplified overview of the relationship between the mental health and physical health
What is the influence of physical activity on mental health/ affect
• Physiological basis
• Neurochemical/neuroplastic/neuroendocrine and vascular effects of exercise/physical activity:
– Increased circulating levels of dopamine, endorphins, serotonin, BDNF
– Increased circulation to brain
– Influence on hypothalamic pituitary axis and physiologic reactivity to stress
• Inflammation
– Reduced systemic inflammation with regular exercise
What are the physiological effects of physical activity and exercise linked to
– Improved mood and concentration
– Improved cognition (especially in elderly)
– Pain relief and improved physical functioning – Feelings of reward/pleasure
• Physiological effects may last several hours after acute bout of exercise and seem to be more significant with > moderate intensity aerobic exercise
What effects does the HPA ( Hypothalamic pituitary adrenal) have?
– Communication of HPA with several regions of brain
including limbic system (motivation and mood), amygdala (fear generation in response to stress), hippocampus (memory formulation, mood + motivation)
– Aerobic exercise appears to increase hippocampal volume
What are overall potential impacts of exercise and physical activity (psychosocial aspects)
- Distraction
- Self efficacy and behaviour reward, autonomous motivation
- Social interaction and overcome negative symptoms
- Improved self esteem and body awareness
- Improved general cognitive function
- Sensory modulation, relaxation and stress relief
- ‘Keystone Habit’ – regular physical activity and structured exercise could help with forming other habits, behaviour change, diet regulation
