Obvious Signs of Mental Illness

A mental disorder or mental illness is a mental health state that alters your thinking, feelings, or behavior (all or a combination of any of these). Such changes result in mental distress and pose challenges in your routine functioning.

Further, mental illness can range from mild to severe in certain cases. Also, individuals with mild mental illness may not show obvious signs of mental illness. However, people suffering from severe mental conditions may show signs of mental illness explicitly. Some of them include social withdrawal and losing interest in others, confusion, issues with concentrating, memorizing, etc.

As per American Psychiatric Association, 19% of U.S. adults face some form of mental illness. Likewise, 24% experience a serious mental illness and 12% suffer from a diagnosable substance use disorder.

Now, there is a wide range of mental disorders or illnesses that people suffer from. Some of the common mental disorders include ADHD, depression, bipolar disorder, OCD, etc. Each of these mental illnesses has their own symptoms and alter an individual’s thinking, feelings, and behavior in various ways.

Similarly, all mental health conditions cannot be outrightly categorized as mental illnesses or mental disorders. This is because they are neurological disorders although the research is still ongoing. Such studies point to the reducing difference between neurological disorders and mental illness.

In this article, we will discuss what is mental illness, the obvious signs of mental illness, and mental illness tests.

What is Mental Illness?

Mental illness is a health condition that includes changes in thinking, emotion, or behavior (all or a combination of some of these.) These mental illnesses lead to distress and cause issues with daily functioning such as work, family, or social activities.

Individuals who have sound mental health:

  • experience healthy relationships,
  • are productive at work, school, and other life activities, and
  • share wholesome relationships with family and friends.

Why is Mental Health Important?

Mental health is the basis of your thought process, feelings, learning, confidence, and the ability to adapt and cope with challenges. It is also important for sharing healthy relationships and one’s personal and emotional health.

However, individuals suffering from mental illness or severe mental conditions face challenges in daily functioning. Further, they go through changes in their thinking, feelings, or behavior which impact their relationships, work, and personal and emotional health.

In addition to this, people with mental illness feel shameful to come out and discuss these issues with family and friends. All thanks to the mental stigma attached with such health conditions, which if left undiagnosed or untreated can prove to be life-threatening.

Also, mental illness can impact anyone irrespective of gender, age, or background location, etc. Despite such facts and statistics, few seek professional help or receive the requisite treatment at the right time.

According to studies, two-thirds of young people do not get the help they desperately need. Similarly, one-third of the children below 18 suffering from severe mental health conditions do not get the requisite mental health care.

One must remember that mental illness is just like any other health condition like blood pressure, diabetes, etc. And just like them, mental disorders are curable.

In fact, there are obvious symptoms of mental illness which if identified can help people seek help at the right time. The following section informs you about some of the warning signs of mental illness.

Obvious Signs of Mental Illness

Some of the significant mental disorders like bipolar disorder or schizophrenia hardly occur suddenly. There may be situations where people showing signs of these mental illnesses might ask themselves ‘Do I have a mental illness or am I overreacting?’

In fact, people closer to such individuals like friends, family, co-workers, teachers, etc play a critical role here. This is because they may be able to identify something unusual in the feelings, thinking, and behavior of individuals who show initial signs of a mental illness.

Therefore, it is important to be aware of some of the obvious signs of mental illness. Knowing these early symptoms can help seek intervention at the right time so as to avoid the mental illness from getting severe.

Causes of Mental Illness

There is not a full comprehension of what causes mental illness. Well, this is not unusual given the complexity of brain functioning and the effects of various mental illnesses on one’s feelings and behavior.

However, scientists consider the following as some of the likely causes of mental illness.

a) Brain’s Biology

As per scientists, mental illnesses are related to alterations in the brain’s neurochemicals.

Scientists are of the view that mental disorders are the outcome of issues neurotransmission or interaction between neurons in the brain.

For instance, the neurotransmitter serotonin is produced less in people having depression as compared to those who don’t. This resulted in the coming up of certain medications for treating depression.

SSRIs (Selective Serotonin Reuptake Inhibitors) are the most common form of antidepressants given for treating depression. Serotonin is a neurotransmitter responsible for uplifting mood, emotions, and inducing sleep. And neurotransmitters are chemical messengers that carry messages between the nerve cells in the brain.

Accordingly, once the serotonin carries a message, the serotonin is typically absorbed by the nerve cells. This is called the reuptake of serotonin into the presynaptic neuron. SSRIs inhibit or prevent such reuptake of the serotonin by the nerve cells so that more serotonin is available in the synaptic region for carrying messages between the nerve cells.

Thus, more serotonin is available in the synaptic region for binding with the receptors on the postsynaptic neuron. Thus, alterations in the neurotransmitters apart from serotonin can take place in depression. This further worsens the condition.

Likewise, there can be alterations in other neurotransmitters like glutamate, dopamine, etc which may impact mental health.

b) Genetics

Genes of an individual also have a critical part in deciding if someone may have a mental illness. Some of the mental disorders that may have a genetic element include ADHD, schizophrenia, bipolar disorder, etc.

For instance, it has been observed that children with ADHD have a higher probability to have a sibling or parent suffering from ADHD. This observation holds up the part genetics play in deciding if an individual is at the risk of having ADHD.

c) Environmental Risk Factors

Certain environmental factors also play an important role in deciding if an individual will suffer from mental illness. These include poor nutrition, being vulnerable to toxic elements like tobacco smoke or lead, a head injury, etc

d) Social Factors

There are a number of social factors that can put individuals at risk of mental illness. Some of these factors are as follows:

  • neglect
  • economic difficulties
  • abuse
  • the mental disorder of parents
  • overcrowding
  • criminal acts of parents
  • a serious parental conflict
  • losing a family member or a dear friend
  • are evident and if you are routine functioning.

Treatment of Mental Illness

When it comes to mental illnesses, the majority of them can’t be cured. However, there are certain means through which the underlying symptoms can be healed so as to reduce them.

Minimizing symptoms of mental illness can help the individual to function well at work, in school, or in society in general.

However, the person going through a mental illness must visit a medical professional so as to start his treatment. This is because the mental health professional will first communicate with the person with mental illness and try to find out the underlying symptoms.

Further, he also tries to understand the period for which such symptoms have existed and in what way have they influenced a person’s life.

In addition to this, the medical professional undertakes physical examination to identify if there exist other health issues. This is because, at times, certain symptoms like mood swings can be the outcome of emotional and neurological symptoms associated with other diseases like terminal illness, etc.

Further, these symptoms can also be the ill effects of certain medications. Thus, after studying the patient fully, the physician charts out a plan for the treatment of mental illness.

Such a treatment can include both psychotherapy and medications depending on the patient’s symptoms and condition.

a) Psychotherapy as a Mental Illness Treatment

Psychotherapy is a mental illness treatment in which a mental health professional communicates with the patient and tries to understand his feelings or issues.

Such dialogue helps the patients in understanding the root cause of the problem and search for solutions. Such therapy may exist in different forms and helps the patients in:

  • resolving their issues in a particular way
  • identify the unusual behavioral patterns, thoughts and alter them
  • acknowledge how their past is influencing their present behaviors
  • learn skills to manage themselves

Further, psychotherapy may take place with the patient, his family, or in a group. Also, it is most effective when combined with medication.

b) Medications for the Treatment of Mental Illness

Medications are another way of treating the symptoms of mental illness. Medications are taken for a specific period, as suggested by the physician., During such times, the health professional keeps a check on the health conditions of the patient.

In case of any side effects, the physician changes the medication which leads to lesser side effects. One must keep in mind that medications do have ill effects and this typically stops people from taking proper medication.

However, be it antibiotics or medications for psychiatric illnesses, each of them has side effects. Therefore, one must consult the physician and understand what medications are they consuming, why are they being given these, and how they will treat their medical condition.

Mental Illness Stigma

One of the greatest sigmas of the current times is the stigma around mental health. Stigma is nothing but when people with certain characteristics are disrespected or disapproved by society due to people having such characteristics.

Accordingly, someone suffering from a mental illness is typically discredited by society and results in their rejection. Statements like “mentally ill people are crazy” or “mentally ill people are dangerous and should be avoided” are all coming out the society’s negative perception of mentally ill people.

Common Stigmas Around Mental Health

Some of the common stigmas around mental health are as follows:

  • people with mental illness are dangerous and must be ignored
  • mentally ill people cannot take their responsibilities and make decisions in their life.
  • such people should try and pull through the mental illness
  • mentally ill people must be taken care of by parents as they are incapable to care for themselves.

All these stigmas are founded on incorrect details. Not all people suffering from a mental illness are a threat to society. In fact, very few people with mental illness pose a danger to society at large.

Therefore, the majority of them can undertake routine tasks like holding a job, attending school, live the way they want to, etc.

You must understand that mental illness is not something one can decide to get rid of. It is much like other diseases like heart disease, diabetes, etc where individuals go through a physical issue in the body.

The stigma around mental health must be overcome for it is more impairing than the illness.

Outcomes of No Mental Illness Treatment

Many people suffering from mental illness do not get the treatment at the right time due to these stigmas. This leads to aggravating or worsening of their mental health conditions.

As per research, 2/3rds of young individuals are not receiving the mental health treatment they need. Likewise, less than 1/3rds of children below 18 years suffering from a serious mental illness do not receive the requisite treatment.

The majority of people are experiencing challenges with regard to mental health because of a number of factors. These include not grabbing the chance at the right time for early identification and prevention, improper medical services, not giving preference to keep resources for such treatments.

All thanks to the stigmas that are attached to mental illness. Not treating mental illness in children can have severe consequences.


For instance:

  • it impacts their ability to learn
  • adolescents suffer and find it difficult to cope with the study pressure
  • increased school drops outs in adolescents which results in them becoming less functional citizens when reaching adulthood
  • interpersonal and psychosocial challenges in young adults post overcoming the illness
  • adults have roots of such illnesses in childhood
  • youth suffering from depression may have a serious illness during adulthood
  • ADHD may continue to exist in adulthood posing legal, social, and occupational challenges
  • mental illness results in premature death or disability
