If you have a mental disorder and are because having children or already have children, i of the questions you are probably asking yourself is whether you could pass your mental disorder on to your kid.

Incidence

According to the National Plant of Mental Health, about 25% of US adults (ages 18 and older) and about 13% of US children (ages 8 to 15) are diagnosed with a mental disorder each twelvemonth. Examples of mental disorders include:

• Depression – Affects 10% of the population.
• Attention Arrears-Hyperactivity Disorder (ADHD) – Affects 5%-eleven% of the population.
• Autism Spectrum Disorder (ASD) – Affects 1 in 68 children.
• Substance use disorders (habit) – Affects ten% of the population.
• Schizophrenia – Affects 1% of the population.
• Bipolar Disorder – Affects 2%-3% of the population.

Diagnosing Mental Disorders

Doctors diagnose mental disorders based on the signs and symptoms of the private patient. Doctors use the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) to assist in diagnosing mental disorders.

There are no genetic tests to confirm a diagnosis of mental disorder. Because experiences and environment play an important role in the development of a mental disorder, no genetic test will ever be able to tell with absolute certainty who volition and who volition not develop a mental disorder.

What does information technology mean if a mental disorder seems to run in my family?

The chance of an private having a specific mental disorder is college if other family members have that aforementioned mental disorder. Even though a mental disorder may run in a family unit, there may be considerable differences in the severity of symptoms among family members. This ways that one person in the family may take a mild instance, while someone else has a more than se​vere case of the mental disorder. Mental disorders, even so, do not follow typical patterns of inheritance.

Causes of Mental Disorders

Most mental disorders are caused by a combination of multiple genetic and environmental factors. This is called multifactorial inheritance. Many other common medical problems such equally type 2 diabetes, obesity, and asthma also undergo multifactorial inheritance.

Environmental factors

Environmental factors contributing to the development of mental disorders include:

• Trauma: Sexual, concrete, and emotional abuse during childhood all pb to an increase in the likelihood of developing a mental disorder. Highly stressful home environments, loss of a loved one, and natural disasters are as well major contributors.
• Emotional harm: Negative schoolhouse experiences and bullying can also result in astringent long-term emotional harm. The realization of these problems has led to anti-bullying campaigns nationwide, and the implementation of these campaigns has placed a larger importance on the overall mental health of school-aged children and teens.
• Substance Corruption: Exposure tobacco, alcohol, and illicit drugs either prenatally or in childhood has been associated with the development of mental disorders beyond just substance use disorders or habit.

Ecology factors alone practise not cause mental disorders. Genetic factors also play a part in developing a mental disorder.

Genetic factors

Genetic factors contributing to the development of mental disorders include:

• Epigenetic regulation: Epigenetics bear upon how a person reacts to environmental factors and may affect whether that person develops a mental disorder equally a result. Epigenetics is not constant over time. This means a gene is not always "on" or "off." There must be the correct combination of environmental factors and epigenetic regulation for a mental disorder to develop.
• Genetic polymorphisms: These changes in our Deoxyribonucleic acid make us unique every bit individuals. A polymorphism alone will not lead to the development of a mental disorder. All the same, the combination of one or more than specific polymorphisms and certain ecology factors may pb to the development of a mental disorder.
• Unmarried gene changes: Rare.

Remember…

Mental disorders are the consequence of both genetic and ecology factors. There is no unmarried genetic switch that when flipped causes a mental disorder. Consequently, it is difficult for doctors to decide a person's risk of inheriting a mental disorder or passing on the disorder to their children. The causes of mental disorders are complex, requiring many interacting genes and environmental factors.
