Are you feeling engulfed by all the mental health information out there?

Confronting the unfamiliar can feel overwhelming, especially when it comes to mental health disorders. Did you know that there are various types of these conditions, including depression, anxiety disorders, and many more? This article is here to guide you through a detailed list of common mental health disorders and their symptoms.

Let?s demystify this subject together and help you become more informed.


mental health disorders


Common Mental Health Disorders


Anxiety disorders, depression, bipolar disorder, post-traumatic stress disorder (PTSD), schizophrenia, eating disorders, disruptive behavior disorders, and neurodevelopmental disorders are some common mental health disorders.

Anxiety Disorders


Anxiety disorders represent a category of mental health conditions marked by excessive fear, worry, and related physical symptoms such as muscle tension or gastrointestinal issues. These disorders can include various forms, such as generalised anxiety disorder (GAD), which leaves individuals with a perpetual feeling of unease beyond normal stress triggers. And there?s a social phobia known as social anxiety disorder that causes an overwhelming fear of social situations leading people to shun them entirely.

The root cause of these disorders often lies in a mix of genetic factors, brain chemistry imbalances, and environmental stressors. However, anxiety conditions are treatable through therapy, medication usage, and lifestyle adjustments. By impacting daily life significantly including relationships and overall well-being, these common mental health issues make it imperative for everyone to understand their signs and seek appropriate help promptly if required.



Depression, also known as major depressive disorder or clinical depression, is a serious mental health disorder that affects your mood and causes persistent feelings of sadness and disinterest. It?s not just about feeling down or being in the dumps; it reflects significant changes in brain functions leading to disrupted thinking, sleep patterns, eating habits, and behaviour.

In some instances, depression symptoms can show up as frequent sadness or anxiety. You may lose interest in activities you once enjoyed and could experience increased irritability or restlessness.

Depression doesn?t discriminate?it occurs alongside other mental illnesses like anxiety disorders creating a complex mix of symptoms that are hard for individuals to handle without help. Therefore, recognising these signs provides vital steps toward diagnosing mental health issues early on for efficient treatment.


Anxiety Disorders


Bipolar Disorder


Bipolar disorder, featured in our mental health disorders list, represents a serious psychiatric disability. This illness thrusts individuals into unusual shifts in mood that swing from extreme highs or mania to devastating lows or depression.

These intense shifts drastically impact both energy levels and behaviour, affecting daily life substantially. Symptoms during manic episodes often include inflated self-esteem, rapid speech, decreased need for sleep, and reckless behaviour. Conversely, depressive symptoms manifest as persistent feelings of sadness coupled with loss of interest in activities and changes in appetite and sleep patterns. Alarmingly these may even extend to thoughts of death or suicide.

Diagnosing mental health diseases like bipolar disorder requires a comprehensive evaluation by a trained professional. The disease affects approximately 2.8% of the adult population in the U.S., across all ages and genders?a startling statistic within our mental ill-health examples.

Despite this prevalence, it?s crucial to note that treatment options exist and are effective: medications such as mood stabilisers can help manage symptoms alongside therapy and lifestyle modifications. With proper treatment adherence and support systems in place?individuals diagnosed with bipolar disorder can lead fulfilling lives irrespective of their struggle with the disease.

Post-Traumatic Stress Disorder (PTSD)


After experiencing or witnessing a terrible event, people may develop post-traumatic stress disorder (PTSD), a mental health condition. It can affect anyone, regardless of age or background, and the symptoms can be debilitating. Some common symptoms of PTSD include flashbacks, nightmares, and severe anxiety. Individuals with PTSD may also have difficulty concentrating, experience changes in mood or behaviour, and may avoid situations that remind them of the traumatic event.

It?s important to note that PTSD often co-occurs with other related conditions such as depression and substance use disorders. Seeking help from professionals who specialise in trauma therapy is crucial for effectively managing and treating this complex disorder.




Schizophrenia is a severe mental disorder that affects approximately 1 in 100 people. It?s a lifelong brain disorder that can cause individuals to interpret reality abnormally. Individuals with schizophrenia might encounter daydreams, fantasies, disarranged discourse, issues with thinking, and an absence of inspiration. Hearing voices and seeing visual hallucinations are common symptoms of this condition. Diagnosing schizophrenia involves a thorough evaluation of these symptoms while ruling out other possible causes. Fortunately, there are treatment options available for those living with schizophrenia. Medication, psychotherapy, and support services can help manage the symptoms and improve the quality of life.

Eating Disorders


Eating disorders are serious mental health disorders that affect a person?s eating habits, thoughts, and emotions. They can have devastating effects on both physical and mental well-being if left untreated. Anorexia nervosa, bulimia nervosa, and binge eating disorders are among the most prevalent types of eating disorders.

Anorexia nervosa sufferers frequently restrict their food intake and express a strong fear of gaining weight. This can lead to dangerously low body weight and severe malnutrition. On the other hand, individuals with bulimia nervosa engage in episodes of binge eating followed by behaviors such as self-induced vomiting or excessive exercise to compensate for the calories consumed.

Binge eating disorder involves recurrent episodes of consuming large quantities of food within a short period accompanied by feelings of loss of control. Unlike bulimia nervosa, individuals with binge eating disorder do not engage in compensatory behaviors.


Eating Disorders


Disruptive Behaviour Disorders


Disruptive behaviour disorders are a group of behavioural problems that can closely resemble ADHD, with symptoms like impulsivity and hyperactivity. Children with these disorders often display ongoing patterns of uncooperative and defiant behavior.

These persistent behavior problems can be associated with other mental health disorders, such as attention deficit hyperactivity disorder (ADHD) and disruptive mood dysregulation disorder. It?s important to recognise the symptoms and behaviours associated with disruptive behaviour disorders so that appropriate support and treatment can be provided. Therapy, behaviour management techniques, medication, and support from family and teachers are common treatment options for these disorders.

Early intervention is key to improving outcomes for affected individuals, as disruptive behaviour disorders can have a significant impact on academic performance, social relationships, and overall well-being.

Neurodevelopmental Disorders


Neurodevelopmental disorders are a category of mental health disorders that primarily affect children. They can have long-term impacts on their cognitive, social, and emotional development. Some examples of neurodevelopmental disorders include intellectual development disorder, autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), learning disabilities, and intellectual disabilities.

These conditions are often diagnosed based on specific symptoms outlined in the Diagnostic and Statistical Manual of Mental Disorders. Research has shown that genetic and environmental factors contribute to the development of neurodevelopmental disorders.

Symptoms of Mental Health Disorders


Mental health disorders have distinct symptoms that can vary depending on the specific condition, such as anxiety disorders, depression, bipolar disorder, PTSD, schizophrenia, eating disorders, disruptive behaviour disorders, and neurodevelopmental disorders.

Anxiety symptoms


Feeling anxious from time to time is normal, but when it starts interfering with your daily life, you may be experiencing symptoms of an anxiety disorder. These disorders are characterised by excessive fear and worry that can manifest in physical symptoms such as restlessness, fatigue, difficulty concentrating, and irritability.

It?s not uncommon for anxiety to cause difficulties breathing or sleeping and even trigger panic attacks. Generalised Anxiety Disorder (GAD) is one specific type of anxiety disorder where individuals commonly experience restlessness, being on edge, difficulty concentrating, and irritability.

Remember that while everyone feels anxious now and then, it?s important to recognise the signs and symptoms of an anxiety disorder so you can seek proper diagnosis and treatment. There are various therapies available to help manage these conditions including medication options as well as cognitive therapies aimed at helping patients gain coping mechanisms.


Depression symptoms


Depression symptoms


Depression symptoms can vary from person to person, but they often include persistent feelings of sadness or low mood. You may find that you no longer enjoy activities that used to bring you pleasure, and your motivation levels may decrease significantly.

It?s also common to experience a lack of energy and interest in daily tasks. Other signs of depression can include changes in appetite or weight, difficulty sleeping or oversleeping, feeling restless or slowed down, having trouble concentrating or making decisions, and even thoughts of death or suicide.

Recognising these symptoms is crucial because depression is a serious medical condition that can have significant impacts on your overall well-being. It?s important to remember that seeking help doesn?t mean weakness; rather, it shows strength and resilience in wanting to overcome this mental health challenge.

Bipolar disorder symptoms


Bipolar disorder is a mental illness that can cause extreme shifts in mood, energy, and daily functioning. The symptoms of bipolar disorder can vary but generally include episodes of mania or hypomania and depression. During manic episodes, individuals with bipolar disorder may feel an intense sense of euphoria, excitement, or happiness. They may also have excessive energy, appear wired or jumpy, and experience insomnia or restlessness.

On the other hand, during depressive episodes associated with bipolar disorder, individuals might feel irritable, and guilty, and have unpredictable mood swings. They may likewise battle with sensations of fretfulness. It?s important to note that the symptoms of bipolar disorder can significantly impact a person?s daily life and functioning. If you suspect that you or someone you know may be experiencing these symptoms associated with bipolar disorder, seek professional help for proper diagnosis and appropriate treatment options are available.

PTSD symptoms


A mental health condition known as post-traumatic stress disorder (PTSD) can occur after witnessing or experiencing a traumatic event. It is important to be aware of the symptoms so that you can recognise them in yourself or others and seek help if needed.

Some common symptoms of PTSD include flashbacks, where you may feel as though you are reliving the traumatic event; distressing images or sensations that keep coming back; irritability and angry outbursts; and problems with sleeping.

These symptoms can significantly affect your daily life and well-being. Remember, there are recognised signs of PTSD, and it?s crucial to reach out for support if you?re experiencing these symptoms.

Schizophrenia symptoms


Schizophrenia is a serious mental illness that affects the way individuals think, feel, and perceive reality. People with schizophrenia may experience a range of symptoms, including cognitive impairments such as problems with attention and concentration.

Other common symptoms include hearing voices and seeing visual hallucinations. It?s important to note that these symptoms are sometimes mistaken for symptoms of depression or other mental illnesses, which can delay proper diagnosis and treatment.

There are different types of schizophrenia, including paranoid schizophrenia and high-functioning schizophrenia characterised by milder symptoms. Diagnosing schizophrenia involves evaluating the presence of specific symptoms and ruling out other possible causes.

Eating disorder symptoms


Eating disorders can have both physical and mental health implications, and it?s crucial to recognise their symptoms for early intervention. Common symptoms of eating disorders include dramatic weight loss, preoccupation with weight and food, and concerns about eating in public. Individuals with dietary problems might eat nearly nothing or to an extreme, prompting different unexpected issues. Emotional, mental, and physical extremes in relation to food and weight characterise these disorders.

Anorexia nervosa, bulimia nervosa, binge eating disorder, avoidant restrictive food intake disorder (ARFID), and other specified feeding and eating disorders are some of the most prevalent types.


Disruptive behaviour disorder symptoms


Disruptive behaviour disorders (DBD) can manifest in a range of symptoms that may significantly impact daily functioning and relationships. These side effects incorporate social segregation, tormenting, vengeance looking for ways of behaving, lying, taking, obliteration of property, accusing others, and effectively opposing power.

Warning signs of DBD may also include aggressive behaviours towards others such as bullying or making threats. It?s important to understand that these behaviours can resemble symptoms of impulsivity and hyperactivity seen in attention deficit hyperactivity disorder (ADHD).

Treatment options for DBD are available which may involve therapy and medication. Early intervention is crucial in effectively managing the symptoms and improving overall well-being for both children and adults affected by disruptive behaviour disorders.




Neurodevelopmental disorder symptoms


Neurodevelopmental disorders encompass a range of conditions that affect brain development and can have lasting impacts on individuals. The symptoms of these disorders can vary widely depending on the specific condition, but they often manifest in difficulties with communication, social interactions, and behaviour.

For example, autism spectrum disorder is one neurodevelopmental disorder that can cause challenges in socialising, communicating effectively, and displaying repetitive behaviours or limited interests.

Attention-deficit/hyperactivity disorder (ADHD), another commonly known neurodevelopmental disorder, may present with symptoms like difficulty sustaining attention, impulsivity, and hyperactivity.


Risk Factors for Mental Health Disorders


Various risk factors can contribute to the development of mental health disorders. Genetics and family history play a significant role, as individuals with close relatives who have mental illnesses are at higher risk themselves.

Traumatic life events, such as abuse or witnessing violence, can also increase susceptibility to mental health disorders. Chronic medical conditions, like heart disease or diabetes, can impact both physical and mental well-being. The burden of managing these conditions can take a toll on an individual?s mental health.

Substance abuse is another common risk factor for mental health disorders. Drugs and alcohol affect brain chemistry and can exacerbate symptoms or trigger the onset of certain conditions. Social isolation and lack of social support are important factors to consider as well. Human connection is crucial for maintaining good mental health, so feeling isolated or lacking a support system can make individuals more vulnerable to developing mental illness.

Understanding these risk factors is essential in promoting early identification and intervention for people experiencing or at risk for mental health disorders. By recognising the various factors that contribute to these conditions, we can work towards reducing the stigma surrounding them and providing better support systems for those affected.

Importance of Health Systems and Social Support


Having a robust health system that prioritises mental health is incredibly important in supporting individuals with mental disorders. Accessible and comprehensive healthcare services can provide the necessary diagnosis, treatment, and support for those experiencing mental health issues.

With proper care, individuals can receive appropriate medications, therapies, and interventions to manage their symptoms effectively. Equally crucial is the role of social support in promoting positive mental health outcomes. Strong connections with family members, friends, and communities can offer emotional support during challenging times.

Social networks provide comfort and contribute to reduced stress levels and improved coping mechanisms. Additionally, having supportive environments at work or school can make a significant difference in an individual?s overall well-being. Employers who prioritise employee mental health initiatives often see reduced healthcare costs while fostering a more productive workforce.

Schools that implement programs addressing students? psychological needs create an environment conducive to learning. Recognising that everyone plays a part in creating a mentally healthy society is important. By educating ourselves about mental health issues and supporting one another through active listening and empathy, we can break down stigmas associated with mental illness and build inclusive communities where it is safe for people to seek assistance when they need it.

Overall, by focusing on both the healthcare system?s capacity to provide effective treatment for mental disorders and cultivating strong social support networks within our communities, we can ensure better outcomes for individuals living with these conditions.

Mental health affects us all; let?s work together toward creating a society that values well-being as much as physical health.

Remember, you are not alone ? there is help available to guide you on your journey towards mental wellness.
