Stress and Mental Health

Stress: Is a stimulus or demand that generates disruption in homeostasis or produces a reaction.

Stress: Is a state of disequilibrium that occurs when there is a disharmony between demands occurring within an individual’s internal and external environment and his or her ability to cope with those demands.

Stressor: a demand from within an individual’s internal and external environment that elicits a physiological and or psychological response.

Stressor: is a source of stress.

Stress can produce adaptive and maladaptive responses.

Responses to Stress

Neurobiological responses: Stimulation of the autonomic nervous system prepares the person for “fight and flight” Physical manifestations of stress include: increased heart beat, increased respiration rate, increased visual acuity.
Behavioural responses: Behavioural responses are determined by client’s coping mechanism/skills. These responses include: Anger, Uncooperativeness, Perceptual disturbances, Sensory disturbances

Determinants of response to stress

Responses are influenced by internal and external resources.

Internal resources include:

Personality traits: determine ones appraisal of events, tolerance, to stress,self esteem and ability to form meaningful relationships. Coping patterns
Biological response to stress are determined by ones cognitive processes, genetic predisposition, developmental stage and biochemical processes that influence the appraisal of the event. Ones stress may be uneventful to another. When an event is appraised as threatening the usual response are anxiety, fear, worry, agitation/restlessness or denial. Neuro-endocrine is mobilized to maintain biological stability (homeostasis)

External resources: close relationship with others that foster support, protection and self reliance during stressful periods. The quality of the relationships influences susceptibility to maladaptive responses and buffers people against distress.

ETIOLOGY OF MENTAL ILLNESS

Many factors are responsible for the causation of mental illness. These factors may predispose an individual to mental illness, precipitate or perpetuate the mental illness

Predisposing factors

These factors determine an individual’s susceptibility mental illness. They interact with precipitating factors resulting in mental illness

These are

Genetic make up
Physical damage to the central nervous system
Adverse psychological influence

Precipitating factors

These are factors that occur shortly before the onset of a disorder and appear to have induced it

These are

Physical stress
Psychosocial stress.

Perpetuating factors

These factors are responsible for aggravating or prolonging the disease already existing in an individual. psychological stress is an example

Thus etiological factors of mental illness can be

Biological factors
Psychological factors
Social factors

Biological factors

Heredity .what one inherits is not the illness or its symptom, but a predisposing to the illness which is determined by genes that we inherit directly. Studies have shown three –fours of mental defectives and one third of psychotic individuals owe their condition mainly to unfavorable heredity.

Biochemical factors; biochemical abnormalities in the brain are considered to be the cause of some psychological disorders. Disturbances in neuro-transmitters in the brain is found to play an important role in etiology of certain psychiatric disorders

Brain damage : Any damage to the structure and functioning of the brain may be due to one of the following causes.

Infection e.g. neuro syphilis, encephalitis ,HIV infection
Injury ;loss of brain tissue due to head injury
Intoxication; damage to the brain tissue due to toxins such as alcohol ,barbiturate ,lead etc
Vascular ;poor blood supply ,bleeding ,(intra-cranial hemorrhage)
Alteration in brain function; changes in blood chemistry that interfere with the brain functioning such as disturbance in blood glucose levels, hypoxia, anoxia and fluid and electrolyte imbalance.
Tumors; brain tumors
Vitamin deficiency and malnutrition ,in particular deficiency of vitamin B complex
Degenerative diseases; dementia
Endocrine disturbances ;hypothyroidism ,thyrotoxicosis etc
Physical defects and physical illness; acute physical illness as well as chronic illnesses with all their handicapping conditions may result in loss of mental capacities.

Physiological changes

It has been observed that mental disorders are more likely to occur at certain critical periods of life namely-puberty, menstruation, pregnancy, delivery, puerperium and climacteric.. These periods are marked not only by also by psychological issues that diminish the adaptive capacity of the individual. Thus the individual becomes more susceptible to mental illness during this period

Psychological factors

It’s observed that some specific personality types are more prone to develop certain psychological disorders. For example those who are unsocial and reserved (schizoid) are vulnerable to schizophrenia when they face adverse situations and psychosocial stresses.

Psychological factors like ,strained interpersonal relationships at home, place of work ,school or college, bereavement ,loss of prestige, loss of job etc

childhood insecurities due to parents with pathological personalities ,faulty attitude of parents (over-strictness, over-leniency), abnormal parent child relationship (over-protection, rejection, unhealthy comparisons) deprivation of child’s essential psychological and social needs etc

Social and recreational deprivations resulting in boredom, isolation and alienationation.

Marriage problems like ,forced bachelorhood ,disharmony due to physical ,emotional, social, educational or financial incapability , childlessness or having too many children etc

Sexual difficulties arising out improper sex education, unhealthy attitudes towards sexual functions, guilt feelings about masturbation, pre and extra –marital sexual relations, worries about sexual perversions.

Stress, frustration, climatic conditions and seasonal variations, seasonal variations and seasonal differences are sometimes noted in the occurrence of mental diseases.

Social factors

Poverty, unemployment, injustice, insecurity, migration, urbanization.

Gambling, alcoholism, prostitution ,broken home ,divorce ,very big family ,religion .traditions political up heals and other social crises .

CLASSIFICATION OF MENTAL ILLENESS

It’s important to classify mental illness because it serves as a guide to Diagnosis and prognosis (outcome)

In psychiatry classification is based on clinical description of disease.

General classification

Neurosis

It means a group of mental disorder which have a combination of symptoms in which there’s is no evidence of organic brain disorder .People who suffer from those conditions don’t lose touch with the external reality ,the behavior may be affected but remains within socially acceptable limits.

In neuroses, there are no hallucinations and delusions.

Patients may have insight and seek help.

Examples of neurosis are:

Anxiety

Disorders occur in various combination of psychological and physical or symptons. Anxiety is vague feeling, worry and tension characterized by excessive fear and apprehension.

Obsessive

Compulsive disorder [OCD] recurred, persistent thought, impulses or images that the pt regards as upgrade, while recognizing them as physical and dissociative problems

Phobic – fear

Panic – Extreme of fear.

PTSD [post – Traumatic stress Disorders]

This is a group of mental symptoms that usually follow a traumatizing experience like war, floods, and epidemics like Ebola, rape, defilement, and accident.

The condition is characterized by severe anxiety persistent disturbing and reoccurring thought or night mares of the experience.

Conversion and dissociation disorder

(Hysteria) present as physical problem present as psychological.

Psychosis:

This is a severe form of mental disorder that is characterized by loss of touch with reality.

A person who has lost touch with reality has abnormal thoughts or beliefs (delusions) and abnormal sensory experience (hallucinations)

She or he may also have disorganized speech and behavior.

Psychoses are divided into function and organic psychosis.

ORGANIC PYSCHOSIS.

Results from identifiable cause e.g malaria, HIV/AIDS, gonorrhea, syphilis, head injury.

Organic mental disorder can be acute or chronic.

Acute organic disorder (delirium)

In this condition there’s fluctuation level of consciousness or clouding of consciousness, hallucinations and loss of memory.

Chronic organic disorder (dementia)

There is no impairment of consciousness but there’s a gross impairment of memory which is due to drainage.

FUNCTIONAL PSYCHOSIS.

Don’t result from early identifiable cause.

No structure damage in brain cell e.g. schizophrenia which is one of the worst form of chronic illness characterized by loss of touch with reality, social withdraw, disturbed thinking, altered perception and behavior.

Affective disorder.

It’s characterized by mood changes i.e. mania and depression.

Depression

Is one of the most mental disorders in the community characterized by persistent low mood, reduced activity and persistent physical complaints.

Mania

Is one of the major mental disorders characterized by excessive happiness increased activity and pressure of speech.

Note: The classification of mental disorders into psychosis and neurosis of an old way of classifying mental disorders though still being used by many clinicians.

Difference between neurosis and psychosis

Neurosis	Psychosis.
A minor form of M.I	Severe form of M.I
no loss of contact with reality	Loss of contact with reality
No abnormal thoughts and beliefs	Abnormal thoughts and beliefs

NEWLY ADOPTED TWO MAIN CLASSIFICATIONS

Diagnostic and Statistical Manual for Classification of Mental disorders (DSM) – American.
International Classification of Disorders (ICD) – WHO.

ICD-10

More general categories.
Generally single axis.

But uses broad aetiology. Uses term neurotic.

DSM-IV-TR

Larger no. of discrete categories. Uses a multi-axial system. Uses term psychotic.

The inclusion of the axes reflect the assumption that most disorders are caused by the interaction of:

Biological
Sociological
Psychological factors.
The patient is assessed more broadly giving a more global in depth picture.

Conditions include

Disorders usually first diagnosed in infancy, childhood or adolescence
Delirium, Dementia & amnestic, & other cognitive disorders
Mental disorders due to a general medical condition
Substance related disorders
Schizophrenia & other psychotic disorders
Mood disorders
Anxiety disorders
. Somatoform disorders
10.Factitious disorders
Dissociative disorders
Sexual & Gender identity disorders
Eating disorders
Sleep disorders
Impulse control disorders not elsewhere classified
Adjustment disorders
Personality disorders
Other conditions that may be a focus of clinical attention

THE FIVE AXES OF THE DSM-IV-TR.

Axis I Clinical syndromes. (All mental disorders & criteria for rating them except personality disorders/mental retardation, also abuse/neglect)
Axis II Personality disorders, Mental retardation. (Life long deeply ingrained, inflexible & maladaptive)
Axis III General medical condition. (Any medical condition that could affect the patients mental state.)
Axis IV Psychosocial & environmental problems. (Stressful events that have occurred within theprevious year)
Axis V global assessment functioning. (How well the patient performed during the previous year)
