Depression results from a complex interaction of social, psychological, and biological factors. People who have gone through adverse life events (unemployment, bereavement, traumatic events) are more likely to develop depression.
Among the suggested causes of the Great Depression are: the stock market crash of 1929; the collapse of world trade due to the Smoot-Hawley Tariff; government policies; bank failures and panics; and the collapse of the money supply.
Introduction. Depression is a global mental health issue that affects individuals to varying degrees across different countries. Some of the most depressed countries include Greece, Spain, Portugal, Palestine, and Tunisia. These countries have depression rates ranging from 6.52% to 5.75%.
Depression. Impacting an estimated 300 million people, depression is the most-common mental disorder and generally affects women more often than men.
Anxiety disorders (such as Social Phobia) are the most common type of disorder, affecting 1 in 6 (17%, or 3.3 million) Australians, followed by Affective disorders (such as Depressive Episode) (8%), and Substance Use disorders (such as Alcohol Dependence) (3. %).
- Depression affects more people than any other mental disorder and is also one of the world's leading causes of disability.
The United States, Colombia, the Netherlands and Ukraine tended to have higher prevalence estimates across most classes of disorder, while Nigeria, Shanghai and Italy were consistently low, and prevalence was lower in Asian countries in general.
Sweden. Sweden has the top positive mental health index which basically gives the mental health status of a given population. However, it wasn't always like this. Mental health policies of Sweden had only focused on two things: people suffering from severe mental health issues and the youth or the children.
Countries with the least depression include several smaller, lower-income countries in South Asia such as Brunei, Myanmar, Timor-Leste and Mali, where less than 2.5% of the population is reported to have a depressive disorder.
Depression is often triggered by a stressful or negative life event. Similarly, a recurrence of a previous depressive episode can be brought on by situational causes. Feelings of depression or anxiety can lead to suicidal thinking.
Research suggests that depression doesn't spring from simply having too much or too little of certain brain chemicals. Rather, there are many possible causes of depression, including faulty mood regulation by the brain, genetic vulnerability, and stressful life events.
Shrinkage Of Several Brain Regions
One of the most common changes seen in a depressed patient's brain is shrinkage, especially in the hippocampus, thalamus, frontal cortex, and prefrontal cortex.
In their lifetimes, about one in five Australians will experience depression. Around the world, depression affects around 300 million people.
Serotonin. Serotonin is another hormone that affects mood, appetite and sleep. It is also a neurotransmitter, which means that it transmits messages between nerve cells. Fewer hours of sunlight means that less serotonin is produced.
Mental health is a key component of overall health and wellbeing (WHO 2021). In any year in Australia, an estimated 1 in 5 people aged 16–85 will experience a mental health disorder (ABS 2022).
The average age of onset for major depressive disorder is between 35 and 40 years of age. Onset in early adulthood may be linked with more depressive episodes, a longer duration of illness, and therefore a more difficult clinical course.
According to this survey, Brazil leads the world in prevalence of anxiety disorders and ranks fifth in depression rates.
According to the report, which used data from Gallup, the top 10 happiest countries are: Finland, Denmark, Iceland, Israel, the Netherlands, Sweden, Norway, Switzerland, Luxembourg and New Zealand.
Borderline personality disorder is one of the most painful mental illnesses since individuals struggling with this disorder are constantly trying to cope with volatile and overwhelming emotions.
Schizophrenia and personality disorders are the most disabling mental health conditions to live with, according to Queensland Brain Institute's Professor John McGrath.
Anxiety disorder is the most treatable of all mental illnesses. Anxiety disorder produces unrealistic fears, excessive worry, flashbacks from past trauma leading to easy startling, changes in sleep patterns, intense tension and ritualistic behavior.
