What Is Mental Illness?

Nearly 1 in 5 Americans suffer from some form of mental health condition. Like any physical disease, there is a range of severity and conditions. Because of this, mental illness is not only challenging to treat and talk about because it can vary so greatly, but also because unlike physical ailments, mental maladies are usually unseen.

Largely, there are two categories of mental disorders: Any Mental Illness (AMI) and Serious Mental Illness (SMI). The first distinction is used to classify any and all mental disorders with varying levels of impairment from mild to severe, while SMI is defined by illnesses that significantly debilitate an individual’s ability to function and carry out daily tasks.

Common Mental Illnesses

  • Attention Deficit Hyperactivity Disorder (ADHD):

    Those with ADHD struggle with their ability to focus, overactivity, or are otherwise unable to control various behaviors. There are 3 different forms of the disorder and the diagnosis of which depends on the symptoms exhibited: inattentiveness, hyperactivity, impulsivity, or a combination of the three.

  • Anxiety:

    There are several different illnesses that fit in this category (such as social anxiety or panic disorder), but the overall umbrella term is Generalized Anxiety Disorder. While anxiety is a normal and healthy response in warranted situations, those suffering with an anxiety disorder live in a heightened state of being even when not in stressful scenarios. Roughly 40 million Americans 18 and older are impacted by a disorder that falls into this division.

  • Bipolar Disorder:

    A condition affecting mood regulation, individuals struggling with bipolar disorder experience intense mood shifts between manic highs and devastating lows. Similar to ADHD, there are several types and diagnoses which depend on both the length and severity of the manic and depressive periods.

  • Body Dysmorphia (BDD):

    This disorder is defined by intrusive and incessant thoughts about one’s physical flaws, both real and perceived, and interferes with their ability to carry out daily functions. Unable to control negative and hurtful thoughts, people with body dysmorphia do not believe others when they reassure them and live in a constant state of self-deprecation.

  • Depression:

    Categorized by feelings of emptiness, hopelessness, and despair, this illness causes people to live perpetually in negative emotion. Often, energy is decreased, activities that once caused joy no longer interest the person, and thoughts of suicide are at a higher risk.

  • Eating Disorders:

    Only recently more studied in greater depth and thus more understood, these conditions have a significant impact on the way an individual relates to food as well as body image. Though there are a few different types of the illness, each stems from a place of internal distress and a desire to control not only the food they’re eating, but their body’s response.

  • Obsessive Compulsive Disorder (OCD):

    Considered an anxiety disorder, OCD is marked by recurrent thoughts, impulses, and/or images that interfere with daily life. As many of these intrusions are ritual-based and repetitive actions, people struggling with OCD spend a lot of time trying to equilibrize their irrational thoughts and physical state of being.

  • Post-Traumatic Stress Disorder (PTSD):

    Caused by the experience of a devastating, dangerous, or otherwise traumatizing event, those living with PTSD experience physical, fear-based responses even after the catalyzing circumstance. A trigger can cause a fight or flight response even when there is no obvious danger.

  • Schizophrenia:

    Due to distorted perception of reality, this condition is one of psychosis. Those suffering with schizophrenia experience hallucinations, delusions, disorganized speech, and jumbled thought processes. Though widely thought to equate to split personalities, individuals with schizophrenia often hear voices or see things that aren’t really there as opposed to the presence of other selves found in multiple personality disorder (also known as Dissociative Identity Disorder or DID).

Forms Of Treatment For Mental Illness

Depending on both the illness itself and the severity, most mental illness treatment involves a combination of psychotherapy and medication. Cognitive Behavioral Therapy (CBT) is common because it helps the individual examine the root cause(s) of various behaviors and therapists work with their clients to develop healthier and more conducive thought patterns. Options like support groups can help those struggling feel less alone while still receiving support and encouragement from a professional. In severe cases of distressed mental health, hospitalization might provide the right level of intensive care.

Medications can help to regulate the chemicals and synapses in the brain that may not be functioning as effectively as they should. Like therapy there are multiple categories of medication used to treat various illnesses and should always involve consultation and prescription from a licensed mental health professional.

COVID’s Impact On Mental Health

The onset and continuation of the COVID-19 pandemic for roughly 2 years has certainly had a negative impact on mental health across the board. However, professionals say that even before 2020, mental health in America, especially among adolescents, was rapidly declining. Mental Health America (MHA), a nonprofit organization committed to addressing and normalizing mental health concerns, reported that suicide ideation among adults has risen every year since 2011-2012.

As of 2022, 4.58% of adults reported serious thoughts of suicide; an increase of 664,000 people from the previous year. Factors like insurance coverage (or lack thereof), an absence of available professionals, and socioeconomic status were in play even before the nation was grappling with the devastation of a global health crisis. The most current statistics MHA provides say that 60% of young people with major depression do not seek out or receive any form of treatment; for adults, the numbers of those struggling with a mental illness but have not received treatment has been steadily increasing since 2011. 2019 saw 24.7% of qualifying adults untreated. While COVID may not have instigated this crisis, it has absolutely exacerbated it.

When Should I Seek Help For My Mental Health?

Part of life is learning, living, and growing through everything thrown our way. Anxiety, sadness, fear, and stress are all normal and healthy human responses; it’s when these thoughts and feelings overtake and cloud our vision that they become intensely problematic and require professional assistance. We often forget the power of the mind and its influence in all that we say and do and when we feel out of control, it feels easier to succumb to the alluring euphoria seemingly provided by drugs and alcohol.
