There are lots of different types of mental health problems. Some examples of common mental health problems are given below:
Some people feel very sad and low in mood for more than two weeks. This is called depression
Some people get more worried than is usual. This is called anxiety
Memory loss and difficulties with thinking, problem-solving or language, severe enough to affect daily life. This is called dementia
Other mental health problems are less common. For example, being addicted to street drugs, or stopping eating due to worries about body image.
What causes mental health problems?
We do not know exactly what causes all mental health problems; however, we do know that some factors make a mental illness more likely.
Changes in the environment (for example, the stress of being homeless or losing a job)
Substance misuse (for example, drinking too much alcohol or taking street drugs)
Being physically unwell can be associated with a mental health problem (for example, if someone has an infection they might become confused)
Mental health problems sometimes run in families (this is called genetic association)
Having a learning disability (for example, trisomy 21, previously known as Down syndrome)
