Study Notes

6th Month of Pregnancy

Eyes begin to move and eyelids open
Baby breathes and cries

7th Month of Pregnancy

Brain controls breathing, swallowing, and body temperature (medulla oblongata)
Baby has the nerve cell capacity for sight, hearing, smell, taste, and vocalization
Grasping and sucking reflexes develop, ensuring newborn survival

26 Weeks of Pregnancy

The "Zone of Viability," where a baby born prematurely has a chance of survival
Premature births increase risk of school and behavioral problems, and psychiatric disorders in adulthood

9th Month of Pregnancy

The fetus can no longer easily float in amniotic fluid.
It curls into a fetal position, usually with the head toward the birthing canal, ready for birth.

Factors Influencing Prenatal Development:

Mom and Mom's environment are linked to the baby through the placenta and umbilical cord.
Teratogens: harmful environmental agents that interfere with normal prenatal development. Can cause birth defects and death. Examples include infections, chemicals, and hormones.
Maternal conditions: physical, social, and psychological conditions, and behaviors of the mother can affect the baby in different ways.

Maternal Nutrition:

Moms need a variety of nutrients for the baby to develop normally. These nutrients are received through the placenta and umbilical cord.
Complications from mal- or under-nutrition: low birth weight, neurological deficits in newborns. This is a big problem in South Africa due to poverty.

Maternal HIV:

Unborn babies can become infected with HIV, either during pregnancy or at birth.
This can be avoided if the mom is taking anti-retroviral medication properly.

Maternal STIs:

STIs like syphilis, gonorrhoea, and genital herpes can impact the baby during prenatal development.

Maternal Stress:

Stress hormones are carried to the baby through the umbilical cord. This can potentially lead to anxiety conditions later in life.

Age of the Mother:

Very young mothers (under 18) and older mothers (over 40) are at a higher risk for complications during pregnancy.

Mom's Physical Health:

Malaria: Potential for low birth weight and parasite exposure for the baby.
Rubella: Can lead to deafness, blindness, and mental retardation in the baby.
Diabetes: Increased risk of a baby having a very high birth weight, stillbirth, and neonatal death.
Hypertension: Can lead to the death of the baby. May require inducing premature birth.

Individuals typically assume critical social roles: marriage, partnerships, parenthood, earning an income, and independence.
Zimbardo's transitional stage: A period between adolescence and adulthood where young people delay taking on traditional adult responsibilities like marriage and parenthood.

Marriage and Partnerships:

Erikson: Focuses on the Intimacy vs. Isolation stage, where individuals navigate the tension between intimacy and isolation.
Informed by beliefs: Those suffering from mental illness were possessed by evil or supernatural forces. Treatment involved driving out these spirits to cure the mental illness.

The Ancient Era:

The first shift to a naturalistic view of mental illness: Hippocrates (father of modern medicine).
Humoral Theory: Imbalance of the four essential humors: blood, phlegm, yellow bile, and black bile.
Mental illness was considered a result of this imbalance.
To cure, remedies focused on rebalancing the humors.
Too much black bile: This was associated with depression.
Naturalistic remedies: solitude, change in diet, abstinence from sexual activity.
The start of a biomedical approach to psychopathology.

The Middle Ages:

Naturalistic approach lost favor: Religious explanations dominated psychopathology.
Supernatural explanations for mental illness resurfaced.
Mental illness was seen as punishment for sins or demonic possession.
The Church relied on exorcisms to cure mental illness.
Witch hunts: Individuals thought to go against Christian faith were accused of being possessed.
They were believed to have supernatural powers that could harm others, subjected to torture and murder.
Formal segregation of those suffering from mental illness: The Church locked up individuals "out of charity" in places like the House of St Mary of Bethlehem (Bedlam).

The Renaissance Era (1400 – 1600):

More humane treatment of those suffering from mental illness.
Ideas related to witchcraft were challenged.
Johann Weyer: He argued that individuals were not possessed by the devil, but instead mentally unstable and not responsible for their actions.
Reginald Scott (1584): His "Discovery of Witchcraft" argued that demonic possessions were medical illnesses.

The Asylum Era:

Increased scientific understanding of mental illness, but also institutionalization.
Patients were housed in asylums known for inhumane treatment:
- Prolonged restraining of patients
- Housing in dark cells
- Torture-like treatments
- Electric shocks
- Bleeding (to get rid of "dangerous fluids")
- Powerful drugs
- Starvation
Emergence of humanitarian reforms in the 1700s: Challenged these inhumane treatments.
Philippe Pinel (France): Advocated for treating patients with kindness and consideration to aid recovery.

Post Traumatic Stress Disorder (PTSD):

Characterized by distressing re-experiencing of a traumatic event, avoidance and emotional numbing, negative alterations in cognition and mood, and increased arousal.
Symptoms must persist for at least a month after the event.
Symptoms can fluctuate over time, and are more apparent during periods of stress.
One of the most frequently diagnosed forms of psychopathology in South Africa due to the high crime rate.

PTSD Symptoms:

Distressing re-experiencing: Mental flashbacks to the scene, recurrent distressing dreams, intrusive thoughts of the event, and hypersensitivity to cues associated with the event.
Avoidance and emotional numbing: Persistently avoiding anything associated with the event, and experiencing a psychic numbing in response to surroundings.
Negative alterations in cognition and mood: Dissociative amnesia, distorted blame of self and others, increased detachment from others or activities.
Increased arousal: Difficulty falling asleep, irritability, and exaggerated startled responses.

Aetiology (Cause) of PTSD:

Major factors:
- The stressor
- The social environment in which the trauma occurred
- Character traits of the individual
- Biological vulnerability of the individual.
Intensity of traumatic reactions depends on:
- Suddenness of the threat
- Duration of the threat
- Amount of fear associated with the event
General findings:
- Young children and the elderly experience greater difficulty coping with traumatic events, increasing their risk of developing PTSD.
- Pre-school subtype of PTSD included in the DSM for children under 7 years old.
- Those with higher vulnerability to anxiety have an increased risk of PTSD.
- Individuals with PTSD experience increased production of catecholamine (hormone that prepares the body for an emergency) while re-experiencing trauma.
- 30% of patients recover.
- 60% continue to experience mild anxiety symptoms associated with trauma.
- 10% remain unchanged or become worse.

Psychodynamic Perspective:

Traumatic events reactivate unresolved conflicts from early childhood.
To cope with trauma, the ego might repeat distressing events to try to master them and reduce anxiety.

Schizophrenia:

Schizophrenia: A disorder characterized by disorganised and fragmented emotions, behaviors, and cognitions.
Shares some symptoms with ukuthwasa (calling to be a traditional healer) and amafufunyana (spirit possession).
Common misconception: It's not a split personality, which is actually Dissociative Identity Disorder (DID). DID involves multiple identities with separate emotional and behavioral characteristics.
Schizophrenia: Involves the splitting of emotions and thoughts, and gross distortions of reality testing.
Psychosis: Psychological disorders characterized by beliefs not based in reality (delusions), perceptions not based in reality (hallucinations), or both.

Two Categories of Schizophrenic Symptoms:

Positive symptoms: Presence of behaviors and feelings not usually present in a normal individual.
- Hallucinations: False sensory perceptions, like seeing or hearing things that aren't there.
- Catatonic behavior: Marked motor abnormalities, like bizarre postures, repetitive movements, and unawareness.
- Disorganized behavior: Inability to persist in goal-directed activity, and inappropriate public behavior.
- Disorganized speech: Incomprehensible speech that is only remotely related to the subject.
- Delusions: Fixed ideas or false beliefs without foundation in reality.
Negative symptoms: Absence of behaviors and feelings that are usually present in a normal person.
