Mental Health Flashcards
info about mental disorders and mental illnesses
what are mental disorders
- disturbances of emotion, thinking, and behaviour
- may occur spontaneously
- severe (problematic to the individual and others)
- lead to functional impairment (interpersonal, social)
- prolonged
- often require professional intervention
- derive from brain dysfunctions
- is rarely, if ever, caused by stress alone
How is the brain involved
The brain is made up of; cells, connections amongst the cells and various neurochemicals. The neurochemicals provide a means for the different parts of the brain to communicate. Different parts of the brain are primarily responsible for doing different things (e.g movement). Most things the brain does depends on many different parts of the brain working together in a network.
If the brain gets sick; neurochemicals messages that help different parts of the brain communicate are not working properly.
One or more of the brain functions will be disturbed . Disturbed functions that a person directly experiences (such as sadness, sleep problems, etc.) are called SYMPTOMS
Disturbed functions that another person sees (such as over activity, withdrawal; etc.) are called SIGNS
Both signs and symptoms can be used to determine if the brain may not be working well. The persons usual life or degree of functioning is also disrupted because of the signs and symptoms
Mental disorders are associated with disturbances in 6 primary domains of brain function;
THINKING OR COGNITION=
- schizophrenia, delirium, dementia
PERCEPTION OR SENSING=
psychotic disorders e.g schizophrenia (hallucinations & delusions)
EMOTION OR FEELING=
-mood disorders e.g depression, dysthymic disorder, bipolar disorder
SIGNALING(being responsive and reacting to the environment)=
-all anxiety disorders (GAD, social phobia, OCD, panic disorder, PTSD)
PHYSICAL=
-eating disorders (bulimia nervosa, anorexia nervosa, binge eating)
BEHAVIOUR=
-ADHD, substance abuse, conduct disorder
Difference between mental distress and mental disorders
Distress: common, caused by a problem or event, usually short lasting, & diagnosis not needed
Disorders: less common, may happen without any stress, often with high severity, usually long lasting, professional help usually needed, needs to be diagnosed
Main cause of mental illness
Can be a lot of reasons
Genetics-the effect of genes on brain development and brain function
Environment-the effects of things outside the brain on the brain such as infection, malnutrition, sever stress etc
Psychotic Disorders
Illnesses characterised by sever disturbances in the capacity to distinguish between what is real and what is not real.
Someone with psychosis exhibits major problems in thinking and behaviour. These include symptoms such as delusions and hallucinations. These result in many impairments that significantly interfere with the capacity to meet ordinary demands of life.
Schizophrenia
-often begins in adolescence and there often may be a genetic component although not always.
_-family history of SCZ, history of birth trauma, history of fatal damage in utero increase
-significant marijuana use may bring on SCZ in young people
What does schizophrenia look like
Delusions (one common delusion is persecutory in which person thinks they are being harmed in some way by another person of force)
Hallucinations (perceptions such as hearing sounds or voices, smelling scents)
Thinking is disorganised in form and in content (for example the pattern of speaking may not make sense to others or what is being said may not make sense).
Behaviour can be disturbed (self grooming and self care may be also compromised)
difficulty with concentration
negative symptoms (flattening of mood, decreased speech and a lack of will)
Criteria for schizophrenia
1 - Positive symptoms as described above (delusions, hallucinations, disorganized thinking)
2 - Negative symptoms as described above
3 - Behavioural disturbances as described above
4 - Significant dysfunction in one or more areas of daily life (social, family, interpersonal, school/work, etc.)
5 - These features must last for at least 6 months during which time there must be at least one month of positive symptoms
What are the different types of Depression
two common kinds of clinical depression, Major Depressive Disorder (MDD) and Dysthymic Disorder (DD). Both can significantly and negatively impact on people’s lives. They can lead to social, personal and family difficulties as well as poor vocational/educational performance and even premature death due to suicide. Additionally, patients with other illnesses such as heart disease and diabetes have an increased risk of death if they are also diagnosed with Depression. This is thought to be due to the physiological effects that Depression has on your body as well as lifestyle effects such as poor self-care, increased smoking and alcohol consumption. Individuals with clinical depression usually require treatment from health professionals but in mild cases may experience substantial improvement with strong social supports and personal counseling.
What is a depressive episode?
A depressive episode is characterized by three symptom clusters: 1. mood 2. thinking (often called cognitive) and 3. body sensations (often called somatic). MDD may present differently in different cultures, particularly in the somatic problems that people present with. Some symptoms include:
Must be severe enough to cause functional impairment (stop the person from doing what he or she would otherwise be doing, or decrease the quality of what he/she is doing)
Must be continuously present every day, most of the day for at least two weeks
Cannot be due to a substance or medicine or medical illness and must be different from the persons usual
state
Depression symptoms and criteria
Mood:
• Feeling “depressed”, “sad”, “unhappy” (or whatever the cultural equivalent of these descriptors is) • Feeling a loss of pleasure or a marked disinterest in all or almost all activities• Feelings of worthlessness, hopelessness or excessive and inappropriate guiltThinking:
• Diminished ability to think or concentrate or substantial indecisiveness • Suicidal thoughts/plans or preoccupation with death and dyingBody Sensations:• Excessive fatigue or loss of energy
• Significant sleep problems (difficulty falling asleep or sleeping excessively) • Physical slowness or in some cases excessive restlessness• Significant decrease in appetite that may lead to noticeable weight loss
FIVE of the above symptoms must be present EVERYDAY for MOST OF THE DAY during the same two week period; ONE of the FIVE symptoms MUST BE either depressed mood or loss of interest or pleasure.
bipolar disorder
- Illness is characterized by cycles (episodes) of depression and mania
- Cycles can be frequent (daily) or infrequent (many years apart)
- During depressive or manic episodes the person may become psychotic
- Suicide rates are high in people with bipolar mood disorder
How is mania different to feeling extremely happy
Mood is mostly elevated or irritable
Many behavioural, physical and thinking, problems
Significant problems in daily life because of the mood
Mood may often not reflect the reality of the environment
Is not caused by a life problem or life event
