Mental illness is a complex topic.
While it is often defined as a mental illness, there are many other types of mental illness.
Here are the three most commonly discussed: mental health disorders, substance use disorders and substance abuse disorders.
The first category, mental health, is defined as: Mental illness that is caused by a disease, illness, disorder or other medical condition.
For example, if you have bipolar disorder and your doctor diagnoses you as having a manic episode, then your doctor may diagnose you with a mental disorder.
Mental health disorders are often linked to other conditions, such as eating disorders, or mental illnesses that are not caused by mental illness at all.
Mental health disorders affect about one in 10,000 people worldwide.
It is a relatively new condition, first being recognised in the early 1990s by the American Psychiatric Association.
The condition was originally defined as depression and anxiety.
Mental illness has been around for a while, but it has been largely overlooked and not recognised by medical professionals.
According to the International Federation of Mental Health, the number of people with a diagnosis of mental health problems is growing rapidly in Australia.
The number of diagnoses has increased from 4.3 million in 2010 to 7.1 million in 2020.
According the Australian Bureau of Statistics, in 2020, there were 1.3 mental health conditions for every 100,000 Australians.
According to the 2016 ABS census, there was 1.6 people with mental health illness for every 10,500 people.
The third category, substance abuse, refers to substance use disorder, a condition that involves a substance abuse problem or misuse.
This includes substance abuse from alcohol or illicit drugs.
In addition, people with substance use problems may have problems with anxiety, depression, eating disorders and addiction.
There are a number of different types of substance use.
Substance use disorders affect up to 1.5 per cent of Australians and they include anorexia, bulimia nervosa, anorexic disorder, compulsive compulsive disorder, depression and bulimic disorders.
People with substance abuse problems may be at high risk of using or abusing alcohol or illegal drugs.
Some individuals who have substance use issues may be unable to work due to their substance use and may not be able to take part in the work or leisure activities they enjoy.
This means they may not work as often, or may not have the motivation to do so.
They may also feel isolated and depressed.
In some instances, these individuals may experience depression and may feel unable to express themselves in a positive way.
In one study, the researchers compared people with both substance use conditions and healthy controls.
The healthy control group comprised 13 people who had never used alcohol or drugs.
The group with substance problems had a significantly lower lifetime prevalence of substance abuse and was significantly more likely to have had a mental health problem.
The researchers also found that individuals who used illegal drugs or alcohol, including cannabis, were significantly more affected by substance use than healthy control subjects.
The participants in the study were also more likely than healthy controls to have tried cannabis in the past 12 months.
While people with these mental health difficulties may feel isolated, they may also experience negative consequences of substance misuse, such the loss of friends and family members.
In 2016, the Federal Government introduced legislation to decriminalise the possession and supply of drugs.
This was in response to recommendations from the Australian National University’s Addiction Centre that the country had a lack of data to determine whether this legislation would have an impact on the uptake of illegal drugs and the number using them.
In 2020, the use of drugs increased by 17.3 per cent in Australia compared to the previous year.
This figure was the highest since the start of the Great Depression.
