Mental health affects how we think, feel, and behave every day. It influences how we handle stress, relate to others, and make decisions. Just like physical health, mental health exists on a spectrum — from thriving to struggling — and at times many people experience challenges that qualify as mental health conditions. 

In this article, we’ll explain what mental health is, explore the most common conditions, look at signs to watch for, and highlight ways to support mental wellbeing.

What Is Mental Health? 

Mental health refers to a person’s emotional, psychological, and social well?being. It influences how we think, feel, and act. Mental health isn’t just the absence of mental illness, it involves being able to cope with life’s challenges, form relationships, and function in daily life. Multiple factors influence mental health, including biology (like genetics), life experiences, and family history.

Understanding mental health helps people recognise when support might be needed and reduces stigma around seeking help.

What Are Mental Health Conditions?

A mental health condition is a pattern of thoughts, feelings, or behaviours that significantly impacts daily functioning, distress, or relationships. These conditions are often diagnosable through clinical criteria and can affect anyone, regardless of age, background, or life situation.

Some people experience mild symptoms occasionally, while others may face persistent challenges that require professional care. Conditions vary widely in type and severity.

Types of Mental Health Conditions

Mental health conditions encompass a broad range of diagnoses. Below are some of the most common types people experience:

Depression

Depression is one of the most prevalent mental health conditions globally. It involves persistent sadness, loss of interest in activities, low energy, and difficulties concentrating.
Globally, depression affects hundreds of millions of people. Data from the World Health Organization shows that depressive disorders impact about 4% of the world’s population, with higher rates in women than men.

Common symptoms include:

• Persistent low mood
• Loss of interest or pleasure
• Trouble sleeping or oversleeping
• Low energy or fatigue

Treatment options for depression include: 

• Personalised therapy and assessment such as a comprehensive psychiatric evaluation followed by counselling, psychotherapy, and cognitive-behavioural therapy (CBT) tailored to individual needs.
• Medical management such as antidepressant medication prescribed and monitored by psychiatrists when appropriate, often alongside therapy.
• Holistic and accessible support that combines lifestyle guidance, preventive strategies, rapid access to care, and telehealth options for convenient treatment.

Anxiety Disorders

Anxiety disorders include a range of conditions where excessive worry and fear interfere with daily life. These may include generalized anxiety disorder (GAD), panic disorder, and social anxiety.

Anxiety disorders are among the most common mental health problems worldwide, with tens of millions of people experiencing them. In 2021, around 359 million people had an anxiety disorder globally, including children and adolescents. 

Treatment options for anxiety disorders include: 

• Tailored therapy and psychological support through specialist counselling, talking therapies, and Cognitive Behavioural Therapy (CBT) help people understand triggers, develop coping strategies, and manage anxiety symptoms effectively. 
• Multidisciplinary care which includes a detailed evaluation and treatment plans which may include both non?medication approaches (with psychologists/psychotherapists) and pharmacologic consultations with psychiatrists, personalised to the individual’s needs.
• Lifestyle guidance through same?week appointments and teleconsultations are available, and clinicians provide guidance on lifestyle measures (like sleep, exercise, and stress management) to support overall anxiety treatment.

Bipolar Disorder: What It Is

Bipolar disorder (formerly called manic depression) is a mood disorder characterised by episodes of high energy and elevated mood (mania or hypomania) followed by periods of depression. It impacts mood, energy, and daily functioning.

Worldwide, an estimated around 0.5% of adults live with bipolar disorder, equating to millions of people. In the UK, about 1.7% of adults have experienced bipolar disorder, with higher screening rates seen in younger age groups. 

Signs & Symptoms:

• High energy, reduced need for sleep
• Inflated self?esteem or risky behaviour
• Low mood, loss of interest
• Changes in sleep and appetite

Treatment options for bipolar disorder:

• Cognitive behavioural therapy focuses on identifying unhelpful or negative behaviours and beliefs and replacing them with positive and healthy ones. It may be helpful in identifying triggers for episodes of bipolar and developing strategies to help you cope with your condition.
• Interpersonal and social rhythm therapy aims to stabilise daily routines and create a more consistent pattern of sleep, exercise and diet.
• Family therapy can help family members to understand more about the condition and how to recognise and manage the early signs.

Post?Traumatic Stress Disorder (PTSD)

PTSD can develop after experiencing or witnessing a traumatic event. While many people experience trauma, only a subset develop PTSD symptoms.

Globally, around 5.6% of adults screen positive for PTSD, and in the UK this rate has increased in recent years.

Common symptoms:

• Flashbacks or intrusive memories
• Avoidance of reminders of the event
• Hyperarousal (being easily startled or tense)

Treatment options for PTSD include: 

• Dementech uses a holistic approach that helps patients re?process traumatic memories so they become part of explicit, narrative memory rather than implicit or somatic memory, which can reduce distressing flashbacks and intrusive symptoms. 
• Evidence?based talking therapies such as psychotherapy, cognitive behavioural therapy (CBT), and family therapy help individuals come to terms with traumatic events, develop healthy coping strategies, and address behavioural and emotional responses to trauma.
• Following detailed assessments with mental health specialists, personalised treatment plans are offered. Dementech also aims for same?week consultations and provides video consultations for those who can’t attend in person. 

Chronic Fatigue Syndrome

This is a complex disorder that cannot be explained by an underlying medical condition. The symptoms include extreme fatigue which does not improve with rest. Scientists are unclear what causes chronic fatigue syndrome although it is believed to be triggered by a combination of factors which may include psychological stress and viral infections.

Symptoms include:

• Extreme exhaustion which does not improve with rest or sleep
• Loss of memory or concentration
• Headaches and/or muscular or joint pain

Treatment options:

Cognitive training involves talking to a counsellor to help you feel more in control of your life. This can help as chronic fatigue brings with it many restrictions and uncertainties. You may also benefit from gentle exercises which you can build up gradually.

Phobias

A phobia is a fear of a specific thing, situation or animal. People can have phobias about a whole range of things, from heights to needles and the symptoms of a phobia can occur suddenly and without warning.

Symptoms can include:

• Breathing difficulties or shortness of breath
• Rapid heartbeat
• Pain or tightness in the chest
• Trembling
• Sweating
• Headaches, nausea or dizziness
• Panic attack

Some of the most common phobias include:

• Arachnophobia (fear of spiders)
• Ophidiophobia (fear of snakes)
• Acrophobia (fear of heights)
• Aerophobia (fear of flying)
• Cynophobia (fear of dogs)
• Social Phobia (fear of being in a social situation)
• Agoraphobia (fear of public places)
• Mysophobia (fear of dirt or germs)

Treatment options for phobias:

Phobias produce a fear response which can be extreme and may interfere with daily living, resulting in anxiety and, in some cases, depression. Psychotherapy has been shown to be effective for phobias and panic disorders and may be used alongside prescribed medication and self-help techniques like meditation and mindfulness.

How to Recognise Mental Health Issues

Recognising mental health changes early can make it easier to get support. Some key signs include:

• Persistent sadness or withdrawal from activities
• Extreme mood changes
• Trouble thinking clearly or concentrating
• Changes in sleep or appetite
• Excessive worry or fear

If these signs interfere with daily life or last for weeks, it may help to talk to a healthcare provider.
