Background: The fact that majority of the mental illnesses have their first manifestation before one reaches adulthood is becoming increasingly clear. Thus, importance of further work in the area is felt considering this early expression. As in childhood and adolescence itself mental illness results in burden, the extent of the problem needs assessment. This can lead to appropriate plan for their prevention and treatment. But, data on which such approach is to be built is sparse.
“The heart of the matter”: Epidemiology is no more about simply counting the numbers. At times, the numbers may be even misleading. It can represent several biases, such as referral services or socioeconomic status, etc. it is more so in child and adolescent psychiatry. The reason being that this population comes across various ‘gatekeepers’ in their way to proper management in the forms of parents, teachers, and paediatricians.
By talking about diagnoses (like ‘acute polymorphic psychotic disorder without symptoms of schizophrenia without acute stress’), psychiatrists may draw criticism and ask for trouble because of allegation of ‘medicalising’ a child's problems. Parents, teachers, and paediatricians may like to call the same problems of the child by different names that can be broadly brought under the rubric of ‘emotional and behavioural difficulties’.
The current classificatory systems, e.g. ICD and DSM do have categories for childhood and adolescence psychiatric disorders. But, they constitute few emotional disorders that are mostly anxiety-related. The same criterion that is applied for adults is used for those mood disorders occurring in children and adolescents. As a result, epidemiological studies find prevalence amounting to nil or minimal. Though, there are suffering and impairment in this population resulting from problems in the mood. Data collected empirically has to be good; based on which to determine how best to extrapolate adult criteria upon children, or should it be applied at all.
“Time they are a changing’”: A new and simple way of classifying childhood and adolescent psychiatric disorders is to categorise them into three groups, namely developmental disorders, disruptive disorders, and emotional disorders. Developmental disorders include intellectual disability, the autistic spectrum, language and reading delays, and enuresis and encopresis. Disruptive disorders include conduct disorder and hyperactivity. Emotional disorders include anxiety, depression, phobias, somatisation, and obsessive-compulsive disorder. It is common to observe comorbidity within each grouping. Across groups, the comorbidity is less.
“Past, passing, and to come”: We studied 26 children up to the age of 15 years, 16 of them were boys, attending psychiatry outpatient department of a newly opened academic medical centre in the initial six months from its inception from February to July 2011. We found nine children with emotional disorders, five with disruptive disorders, and ten with developmental disorders; comorbidity in our study was equal in both within each grouping and across groups.
We are also studying children and adolescents up to the age of 18 years getting admitted in a newly opened child and adolescent psychiatry unit in the initial three months from its inception from October to December 2015.
Apart from dividing the childhood and adolescence psychiatric disorders (diagnosed as per the tenth revision of the International Statistical Classification of Diseases and Related Health Problems) into the three groups of developmental, disruptive, and emotional disorders, as well as observing inter- and intra-group clustering, we also plan to apply tool such as MINI-KID to improve the validity and reliability of such a classificatory system.
Conclusions: There has been enormous advance in the classification of the childhood and adolescence psychiatric disorders and the empirical basis on which to support the current classificatory scheme is growing stronger; but, at the same time, more and more data are required toward this end for prevention and treatment of these conditions in this age group, as well as there are obstacles which are considerable to overcome for these approaches to become major steps forward.
