Several causes of mental health disorders in psychological abnormality
Mental health disorders are elicited by several influences such as the following:
- Inherited or inner traits. Mental health disorders are typical in people with close relatives who have these kinds of disorders as well. Some genes have been found to make some people susceptible to having this kind of disorder.
- Environmental exposures before childbirth. If the child is exposed to environmental stressors, toxins, inflammatory disorders, alcohol or drugs while in the womb can sometimes be associated with mental health disorders.
- Brain chemistry. Brain chemicals in the brain are called neurotransmitters which pass messages from the brain to the other nerves in the body. When these neurotransmitters may become less or more in the nervous system, this may lead to mental health disorders.
Diagnosis of mental health disorders
To make a diagnosis of a mental health disorder, the doctor will first make you take these kinds of tests which are the following:
- A physical test. This kind of test will help the doctor to take note if there are physical disorders that may be causing your mental health symptoms.
- Lab or blood tests. These kinds of tests can include checking for alcohol or drug use before mental health symptoms started.
- A psychological assessment. A mental health professional will inquire about your components of mental wellbeing such as thoughts, emotions, and behaviours. You may also be asked to take a psychological test to answer these inquiries.

In taking the effort and time to make a precise diagnosis, it would lead the patient to the right treatment.

Some of the most famous medications in this class are the following:
- Antidepressants. As stated in the name, antidepressants are used to treat depression and other mental health conditions as well. These medications can help reduce the symptoms fo depression such as anhedonia or lack of pleasure in doing pleasurable activities and heaviness which causes lack of energy. These medications do not cause addiction or tolerance in the patient.
- Anti-anxiety medications. As stated in the name, these medications are used to cure anxiety symptoms in disorders. These medications have also been used to minimize insomnia and agitation. Long-term medications of this class are antidepressant medications that can help anxiety. Fast-acting anti-anxiety drugs help with short-term relief but they also have the susceptibility to cause tolerance so ideally they’d be used short term for patients.
- Mood-stabilizing medications. Mood stabilizers are most typically used to treat bipolar disorders which are mood disorders that involve switching episodes of mania or hypomania and depression. Sometimes these medications are used with antidepressant medications to treat depressive disorders.
- Antipsychotic medications. These medications are used to stabilize the psychotic symptoms in psychotic symptoms such as schizophrenia. Since these medications can help in stabilizing psychotic symptoms, they have been used to cure psychotic symptoms in some mental health disorders such as bipolar disorder and depression.
Psychotherapy is called the talking cure where individuals will talk about their mental health symptoms.

Psychotherapy can be effective even if you only took it for a few weeks but some of these therapies will be a lifetime occurrence due to the severity of the symptoms.
These therapies can be in two forms such as individual where you will be speaking to the therapist or group therapy where you will be speaking with a group or your family.
It is also important that you choose the right therapist for you since you have to make sure that he or she is willing to listen.
It is also important that you choose a therapist who specializes in your mental health disorder so that you are confident that he or she knows what to do.
Brain-stimulation interventions are used for people who have depression or erratic disorders.
These interventions are only used when other forms of treatment have not shown any effects.
Brain-stimulation interventions include electroconvulsive therapy, deep brain stimulation, transcranial magnetic stimulation and vagus nerve stimulation.
You should be able to understand the risks and benefits of these treatments before getting yourself involved with this treatment.
Hospital and residential treatment programs
People with severe mental health disorders are tended to in psychiatric hospitals.
This is recommended to people who can’t take care of themselves or may have a risk for danger to themselves or others.
Depending on the severity of symptoms that needs immediate psychological intervention, your program options will include 24-hour inpatient care, residential treatment or day hospitalization which provides a temporary supportive place to live.
Another program option is an intensive outpatient intervention for patients who are assessed to be somewhat able enough to still live a normal life despite their mental health disorders.

Substance abuse tends to become comorbid with other mental health disorders.
This symptom can minimize the effects of other forms of treatment.

In some situations, a loved one may be asked to assist you in your treatment to guide you towards mental wellbeing.

Collaborating with your mental health professionals and loved ones can help you find the treatment options that can help you.
