Key facts • 1 in every 8 people in the world live with a mental disorder • Mental disorders involve significant disturbances in thinking, emotional regulation, or behaviour • There are many different types of mental disorders • Effective prevention and treatment options exist • Most people do not have access to effective care A mental disorder is characterized by a clinically significant disturbance in an individual’s cognition, emotional regulation, or behaviour. It is usually associated with distress or impairment in important areas of functioning. There are many different types of mental disorders. Mental disorders may also be referred to as mental health conditions. The latter is a broader term covering mental disorders, psychosocial disabilities and (other) mental states associated with significant distress, impairment in functioning, or risk of self-harm. This fact sheet focuses on mental disorders as described by the International Classification of Diseases 11th Revision (ICD-11). In 2019, 1 in every 8 people, or 970 million people around the world were living with a mental disorder, with anxiety and depressive disorders the most common (1). In 2020, the number of people living with anxiety and depressive disorders rose significantly because of the COVID-19 pandemic. Initial estimates show a 26% and 28% increase respectively for anxiety and major depressive disorders in just one year (2). While effective prevention and treatment options exist, most people with menta...

Many people have mental health concerns from time to time. But a mental health concern becomes a mental illness when ongoing signs and symptoms cause frequent stress and affect your ability to function. A mental illness can make you miserable and can cause problems in your daily life, such as at school or work or in relationships. In most cases, symptoms can be managed with a combination of medications and talk therapy (psychotherapy). Symptoms Signs and symptoms of mental illness can vary, depending on the disorder, circumstances and other factors. Mental illness symptoms can affect emotions, thoughts and behaviors. Examples of signs and symptoms include: • Feeling sad or down • Confused thinking or reduced ability to concentrate • Excessive fears or worries, or extreme feelings of guilt • Extreme mood changes of highs and lows • Withdrawal from friends and activities • Significant tiredness, low energy or problems sleeping • Detachment from reality (delusions), paranoia or hallucinations • Inability to cope with daily problems or stress • Trouble understanding and relating to situations and to people • Problems with alcohol or drug use • Major changes in eating habits • Sex drive changes • Excessive anger, hostility or violence • Suicidal thinking Sometimes symptoms of a mental health disorder appear as physical problems, such as stomach pain, back pain, headaches, or other unexplained aches and pains. When to see a doctor If you have any signs or symptoms of a mental il...

Human anxiety is a grave mental health concern that needs to be addressed in the appropriate manner in order to develop a healthy society. In this study, an objective human anxiety assessment framework is developed by using physiological signals of electroencephalography (EEG) and recorded in response to exposure therapy. The EEG signals of twenty-three subjects from an existing database called “A Database for Anxious States which is based on a Psychological Stimulation (DASPS)” are used for anxiety quantification into two and four levels. The EEG signals are pre-processed using appropriate noise filtering techniques to remove unwanted ocular and muscular artifacts. Channel selection is performed to select the significantly different electrodes using statistical analysis techniques for binary and four-level classification of human anxiety, respectively. Features are extracted from the data of selected EEG channels in the frequency domain. Frequency band selection is applied to select the appropriate combination of EEG frequency bands, which in this study are theta and beta bands. Feature selection is applied to the features of the selected EEG frequency bands. Finally, the selected subset of features from the appropriate frequency bands of the statistically significant EEG channels were classified using multiple machine learning algorithms. An accuracy of 94.90% and 92.74% is attained for two and four-level anxiety classification using a random forest classifier with 9 and...

Anxiety is a psychological and physiological state characterized by cognitive, physiological, and behavioral components. It is described as the “apprehensive anticipation of future danger or misfortune accompanied by a feeling of worry, distress, and/or somatic symptoms of tension” (American Psychiatric Association [APA] Several types of assessment measures can be used in the evaluation and treatment of anxiety. Screening questions and instruments are often used first when anxiety is suspected in a clinical setting. These can include single-item questions or brief screening instruments...

This video has been medically reviewed by Types of Cognitive Behavioral Therapy CBT encompasses a range of techniques and approaches that address our thoughts, emotions, and behaviors. These can range from structured psychotherapies to self-help practices. Some of the specific types of therapeutic approaches that involve cognitive behavioral therapy include: • Cognitive therapy centers on identifying and changing inaccurate or distorted thought patterns, emotional responses, and behaviors. • Dialectical behavior therapy (DBT)addresses destructive or disturbing thoughts and behaviors while incorporating treatment strategies such as emotional regulation and mindfulness. • • Rational emotive behavior therapy (REBT) involves identifying irrational beliefs, actively challenging these beliefs, and finally learning to recognize and change these thought patterns. We've tried, tested, and written unbiased reviews of the Benefits of Cognitive Behavioral Therapy The underlying concept behind CBT is that thoughts and feelings play a fundamental role in behavior. For example, a person who spends a lot of time thinking about plane crashes, runway accidents, and other air disasters may avoid air travel as a result. • Research indicates that cognitive behavioral therapy is the leading evidence-based treatment for • CBT has been proven helpful in those with insomnia, as well as those who have a medical condition that interferes with sleep, including those with pain or • Cognitive behaviora...
