Mental Health Basics and Social Impact

Think of mental health as a continuum rather than just "healthy" or "unwell" - everyone sits somewhere on this sliding scale. Currently, 1 in 4 British adults and 1 in 10 children receive mental health diagnoses, with numbers rising due to social media, COVID-19, and increased awareness.

Stigma creates massive barriers both before and after diagnosis. Before seeking help, people often feel like attention-seekers or think "it's all in their head," which stops them getting support. After diagnosis, constant labelling and assumptions can create a self-fulfilling prophecy where people start behaving exactly as others expect them to.

The ripple effects spread far beyond the individual. Workplace productivity drops, communities may face anti-social behaviour, and public services face increased demand. However, care in the community (treating patients at home rather than hospitals) helps people reintegrate into society whilst reducing strain on healthcare systems.

Key Point: Mental health definitions have changed dramatically over time - homosexuality was removed as a mental disorder in 1990, showing how our understanding evolves.

Schizophrenia: Understanding the Condition

Schizophrenia affects 1% of the population and typically emerges by age 40, hitting men and women equally. The symptoms include delusions, hallucinations, disorganised speech, and catatonic behaviour - though 25% of people recover fully.

The dopamine hypothesis suggests that high dopamine levels cause symptoms like erratic behaviour and hallucinations. Brain scans reveal structural differences: smaller hippocampus affects emotions, reduced temporal lobe volume causes auditory hallucinations, and restricted blood flow to the prefrontal cortex makes organisation difficult.

Social drift theory explains why schizophrenia appears more common in lower social classes. The condition itself - not social status - may cause people to drift downwards due to becoming unmotivated, neglected, and facing discrimination.

Daniel's study used brain scans on 10 patients, finding that amphetamines improved performance by increasing prefrontal cortex activity. However, critics argue this research is reductionist, culturally biased, and potentially harmful to participants.

Reality Check: Establishing cause and effect is tricky - does low social status cause schizophrenia, or does schizophrenia cause people to lose social status?

Depression: Causes and Modern Research

Depression hits 4-10% of England's population, with women (33%) affected nearly twice as much as men (19%). Half of all cases are diagnosed in childhood, making early understanding crucial. Symptoms include persistent low mood, hopelessness, zero motivation, and suicidal thoughts.

The ABC model explains depression through irrational thinking patterns. An Activating event triggers certain Beliefs (rational or irrational), leading to emotional Consequences. This model supports cognitive behavioural therapy but gets criticised for being reductionist and potentially blaming patients for their illness.

Social rank theory suggests depression evolved as an adaptive response to losing social competition. When humans lose status or resources, depression makes them "yield to winners," maintaining social peace. However, this theory struggles to explain why wealthy people also experience depression.

Tandoc's study of 736 US students found heavy Facebook users showed stronger envy, with Facebook envy leading to depression rather than causing it. Critics highlight cultural bias, social desirability issues, and age limitations in this research.

Think About It: Is feeling depressed after losing your job actually an irrational response, or could it be completely rational?

Treatments and Assessment Methods

Anti-psychotic medications treat schizophrenia by blocking dopamine receptors. Typical antipsychotics reduce positive symptoms but cause serious side effects like seizures and tremors. Atypical antipsychotics work similarly but also affect serotonin, causing weight gain instead of neurological problems.

Anti-depressants (SSRIs) increase serotonin levels by blocking reuptake at the pre-synaptic neuron. More serotonin in the synapse means better neural communication and improved mood - though they don't work for everyone.

Cognitive Behavioural Therapy (CBT) uses the ABC model to challenge irrational thoughts over 5-20 sessions. Patients keep thought diaries to identify negative patterns, then work to develop more positive perspectives. This approach helps schizophrenia patients re-evaluate voices and depression patients tackle negative thinking.

Assessment tools include brain imaging (PET scans show medication effects), the Wisconsin Card Sort (tests frontal lobe function in schizophrenia), and Beck's Depression Inventory (measures depression severity through multiple-choice questions covering different symptoms).

Bottom Line: Combining medication with talking therapy often produces the best outcomes - there's no one-size-fits-all solution to mental health treatment.
