Mental health problems are a significant issue in the world, affecting millions of people globally. Mental illnesses are often distressing, and they can significantly impact the quality of life of sufferers and their loved ones.

While some conditions are more treatable than others, some are deadly. Here are the top five deadliest mental disorders.

1. Anorexia Nervosa

Anorexia nervosa is an eating disorder characterized by an obsessive fear of gaining weight, leading to severe food restriction, weight loss, and an unhealthy and dangerously low body weight.

This disorder has the highest mortality rate of all psychiatric conditions; up to 20 percent of sufferers die due to the disorder’s complications, with suicide being the leading cause of death. The disorder can cause severe physical complications, such as electrolyte imbalances, low blood pressure, heart problems, and organ failure, which can lead to death.

2. Schizophrenia

Schizophrenia is a severe mental disorder that affects about one percent of the population. It is a chronic illness that can cause distorted thinking, delusions, hallucinations, and abnormal behavior.

While schizophrenia is not fatal itself, its complications can be deadly. Individuals with schizophrenia have a higher risk of suicide, substance abuse, and other physical health problems, such as metabolic disorders and cardiovascular problems.

Schizophrenia sufferers also have a reduced life expectancy compared to the general population, with an average of 10 to 20 years less.

3. Major Depressive Disorder

Major Depressive Disorder (MDD), also known as clinical depression, is the most common mood disorder and a leading cause of disability worldwide.

MDD is a severe and chronic mental health condition that causes persistent feelings of sadness, hopelessness, and loss of interest in activities, leading to a decrease in the quality of life and functioning. While MDD is not always fatal, it can lead to suicide and other severe complications, such as heart disease, stroke, and cancer. Individuals with MDD have an increased risk of premature death due to physical health problems.

4. Post-Traumatic Stress Disorder

Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can develop after experiencing or being exposed to a traumatic event, such as physical violence, sexual assault, natural disasters, or military combat.

PTSD can cause significant emotional distress, including flashbacks, nightmares, hypervigilance, and avoidance behaviors, leading to a decreased quality of life. PTSD also increases the risk of suicidal ideation and suicide attempts; it is estimated that up to 20 percent of individuals with PTSD will attempt suicide at some point.

The condition also increases the risk of other health problems such as substance abuse, cardiovascular disease, and cognitive impairment.

5. Substance Use Disorder

Substance Use Disorder is a mental health condition characterized by persistent and problematic use of drugs or alcohol despite negative consequences.

Substance abuse and addiction are widespread and can significantly impact physical health, social functioning, and quality of life. Substance Use Disorder can lead to several health problems, such as liver disease, stroke, heart disease, and cancer. It can also cause mental health problems such as depression and anxiety.

Substance abuse also increases the risk of accidents, homicides, and suicide, making it a deadly mental health disorder.

Conclusion

The above-listed mental disorders can all be fatal, either due to the condition itself or severe health complications or risk behaviors resulting from the disorder.

These disorders are devastating and can significantly impact the lives of those affected and their loved ones. Early identification, diagnosis, and appropriate treatment are essential in managing these conditions and reducing the risk of complications and premature death.
