We all feel some anxiety at some time or other. Anxiety may serve as an alerting signal, warning us of external /internal threats and consequently acting as a prompt to take appropriate action. When anxiety is very severe and present even when there is no threat of any kind, then it interferes with our functioning and can become an illness. In this circumstance, anxiety becomes a disorder characterised by an unpleasant emotion with feelings of fear, threat and impending danger and can be associated with numerous bodily symptoms like breathlessness, trembling, tightness in throat, dry mouth, racing heart and nausea/vomiting. There are varieties of anxiety disorders like panic attacks, phobias (unhealthy fear of something), agoraphobia (fear of open spaces), social anxiety, post-traumatic disorder and obsessive compulsive disorder. Anxiety can often be associated with a depressive episode. Anxiety disorders are very common and if unrecognised and untreated, can cause severe disability. Treatment Self help: learning techniques like relaxation, distraction and education Cognitive Behavioural Therapy (CBT) Medication.

ADHD is a behavioural disorder characterised by problems with concentration and impulse control. The typical symptoms of inattention, hyperactivity and impulsive behaviour may all be present to an equal degree or one symptom may be dominant with the other two present to a greater or lesser extent.

Schizophrenia is a serious mental disorder that affects about 1% of the general population. It is a complex illness characterised by ‘psychosis’, a word used to describe disorder of thoughts (e.g. delusions - false beliefs held in spite of evidence that they are not real), perceptions (e.g. hallucinations - seeing, hearing or feeling things which are not there), disorganised speech and grossly disorganised behaviour, which are not experienced by others and which are not seen as abnormal by the sufferer. These four symptoms are often referred to as the ‘Positive Symptoms’ of schizophrenia because they are the result of the disease process. The fifth group of symptoms: withdrawal, decreased ability to feel pleasure, lack of energy, and flat affect, are referred to as ‘Negative Symptoms’ because they represent a loss of normal functions. Schizophrenia affects different people in different ways. Some people may experience only a few short episodes and then fully recover. For others it lasts throughout their lives and needs to be treated like any other physical illness such as asthma or diabetes. It is important that schizophrenia is treated as soon as it is diagnosed by a psychiatrist to prevent long-term disability and loss of function. Treatment Schizophrenia may be treated using a number of different approaches: Use of antipsychotic medication Psychosocial education programs e.g. education, support, counselling and assistance to return to job/studies/performing daily tasks Ongoing support e.g. housing, monitoring of treatment, support groups.

This is a mood disorder in which both depressive (persistent low mood) and manic (elevated or high mood) episodes are experienced. It is usually a recurring (i.e. keeps coming back) disorder that can cause a lot of havoc in all aspects of a person’s life. People with this disorder will experience periods of extreme mood changes but also periods of stable mood during which they may be able to return to everyday routines. These changes of mood can be very extreme and occur for no apparent reason. Different people will experience this disorder in different ways; some may have few episodes, others many, and symptoms may vary from mild to severe. When severely depressed or elevated, a person can become ‘psychotic’ i.e. lose touch with reality. Treatment Usually by medication (antidepressants if depressed and mood stabilisers if depressed and manic) A combination of counselling and psychotherapy (‘talking therapy’) may hasten recovery Hospitalisation may be required for those who are very unwell and are posing a risk to themselves or to others.
