Welcome to Psychological Problems!
In this chapter, we are going to explore how mental health affects people and society. We often talk about physical health, but our mental health—how we think, feel, and act—is just as important. Don't worry if some of the terms seem big at first; we will break them down into bite-sized pieces using everyday examples!
1. Understanding Mental Health
Mental health isn't just the absence of a problem. It’s about how well you handle life's "ups and downs."
Characteristics of Good Mental Health:
- Positive engagement: Being able to take part in activities and enjoy the company of others.
- Effective coping: Being able to handle stress or challenges without feeling completely overwhelmed.
How Mental Health Has Changed Over Time
The way we see mental health is changing. In the past, there was a lot of social stigma (shame or fear) surrounding these topics. Today, there is increased recognition, meaning more people understand that mental health problems are medical issues, not "weaknesses."
Analogy: Think of mental health like a weather system. Sometimes it’s sunny (good health), and sometimes there are storms (problems). Just because it’s stormy doesn't mean the sky is "broken"—it just needs the right conditions to clear up.
Did you know? Different cultures have different cultural variations in beliefs. Some cultures might see mental health through a spiritual lens, while others focus strictly on biology.
Quick Review: Mental health is about coping and engaging. Today, we have less stigma and a better understanding of modern challenges like isolation (feeling alone).
2. The Impact of Mental Health Problems
When someone has a significant mental health problem, it doesn't just affect them—it ripples out into the world.
Individual Effects
- Damage to relationships: It can be hard to communicate with friends or family.
- Difficulties coping: Everyday tasks like getting dressed or going to work can feel impossible.
- Physical wellbeing: Stress or depression can lead to physical illness or lack of sleep.
Social Effects
- Social care: The government needs to provide more support and doctors.
- Economy: If people are too unwell to work, it costs the country money.
- Crime rates: Sometimes, though not always, untreated problems can lead to an increase in crime.
Key Takeaway: Mental health problems affect the person’s body and life, but also the economy and the community around them.
3. Clinical Depression
It is very important to know the difference between being "unhappy" and having "clinical depression."
Types of Depression
- Unipolar Depression: This is when a person stays at one "pole" (the low end). They feel constant sadness and low mood.
- Bipolar Depression: This is when a person swings between two poles: extreme lows (depression) and extreme highs (mania).
- Sadness: This is a normal human emotion that usually goes away after a short time. Clinical depression lasts much longer and stops you from functioning.
Diagnosing Depression (ICD)
Doctors use a book called the International Classification of Diseases (ICD) to diagnose depression. They look for:
- Low mood (feeling empty or sad).
- Reduced energy levels (feeling constantly tired).
- Changes in sleep: Sleeping too much or not being able to sleep.
- Appetite levels: Eating much more or much less than usual.
- Decrease in self-confidence: Feeling worthless or "not good enough."
Memory Aid: Think of the ICD as a "Checklist for Doctors." If you have enough "checks" on the list for a long period, it is diagnosed as clinical depression.
4. Why Does Depression Happen?
Psychologists look at Nature (biology) and Nurture (environment) to explain depression.
The Biological Explanation (Nature)
This theory suggests an imbalance of neurotransmitters. Neurotransmitters are chemical messengers in the brain. Specifically, scientists look at Serotonin. If you have too little serotonin, your brain can't pass "happy" or "calm" messages effectively.
The Psychological Explanation (Nurture)
This theory focuses on how we think.
- Negative Schemas: A schema is like a mental "template." If you have a negative schema, you see the world through "dark-tinted glasses," expecting the worst from every situation.
- Attributions: This is how we explain why things happen. Someone with depression might blame themselves for every bad thing (Internal attribution) and think things will never get better (Stable attribution).
Common Mistake: Don't think it's only one or the other! Most psychologists believe depression is a mix of both biology and the way we think.
5. Treating Depression
We can treat the body or the mind.
Biological Treatment: Antidepressants
These medications work by increasing the levels of serotonin in the brain. They help "reset" the chemical balance.
Psychological Treatment: CBT
Cognitive Behaviour Therapy (CBT) helps patients recognize their negative thoughts and change their behavior. Step-by-step: 1. Identify the negative thought (e.g., "Nobody likes me"). 2. Challenge the thought with evidence (e.g., "My friend called me yesterday"). 3. Replace it with a more balanced thought.
The Wiles' Study: This research showed that for people who didn't get better with medication alone, adding CBT was much more effective. This suggests a holistic approach (treating the whole person) is better than a reductionist approach (treating just one part).
6. Addiction
Addiction is when a person loses control over using a substance or doing an activity.
Key Differences
- Addiction/Dependence: You feel you need the substance to feel normal. If you stop, you get withdrawal symptoms.
- Substance misuse/abuse: Using a drug in a way that is harmful (like drinking too much in one night), but not necessarily being "hooked" on it yet.
How Doctors Diagnose Addiction (ICD)
According to the ICD, a person has a "dependence syndrome" if they have:
- A strong desire or compulsion to use the substance.
- Difficulty in controlling use (cannot stop once they start).
- A higher priority given to the substance than to other activities (like hobbies or work).
- Using it despite harmful consequences (like health or money problems).
7. Why Does Addiction Happen?
The Biological Explanation (Nature)
Some people have a genetic vulnerability. This means they are born with genes that make them more likely to become addicted. Kaij’s twin study: Kaij studied twins and found that if one identical twin was an alcoholic, the other was much more likely to be one too, compared to non-identical twins. Because identical twins share the same genes, this proves biology plays a big role!
The Psychological Explanation (Nurture)
Peer Influence: We are social creatures. If our friends smoke or drink, we are more likely to do it to "fit in" or because we see it as normal behavior. This is the Social Learning Theory in action!
8. Treating Addiction
Aversion Therapy
This is based on Classical Conditioning. The goal is to make the person feel "yucky" about their addiction. For example, an alcoholic might take a drug that makes them feel very sick if they drink alcohol. Eventually, their brain associates alcohol with vomiting instead of pleasure.
Self-Management Programmes
These are peer-led groups like Alcoholics Anonymous (AA).
- They often use 12-step recovery programmes.
- The focus is on the "whole person" and getting support from others who have been through the same thing.
Quick Review: - Reductionist view: Addiction is just a chemical/genetic problem. Treat it with drugs or aversion. - Holistic view: Addiction involves the person's feelings, their friends, and their social life. Treat it with support groups and therapy.
Final Summary Takeaway
1. Mental health is about coping and is viewed differently across cultures.
2. Depression is marked by low mood and energy; it can be explained by low serotonin or negative schemas.
3. Addiction involves a loss of control and can be caused by genes or peer pressure.
4. Treatments can be biological (meds/aversion) or psychological (CBT/12-steps). A holistic approach is usually best!
