Child Psychiatry

1. Attention  deficit  hyperactivity  disorder  –  Three components  with onset  before  12 years  of  age  include inattention  and  hyperactivity/impulsivity.   Children  with ADHD may attack  a  test  rapidly, but answer  only the  first two  questions.  They may  be  unable  to  wait  to  be  called  on in  school  and  may  respond  before  everyone  else.  At home,  they  cannot  be  put  off  for  even  a  minute.  Children with ADHD are  often  explosive  or  irritable.  The  irritability may be  set  off  by relatively  minor  stimuli,  which  may puzzle  and  dismay the  children.  They are  frequently emotionally labile  and  easily set  off  to  laughter  or  to tears; their  mood  and  performance  are  apt  to  be  variable and  unpredictable.  Impulsiveness  and  an  inability  to delay gratification  are  characteristic.  Children  are  often susceptible  to  accidents.  Ref:  Synopsis  of  Psychiatry, Kaplan and Sadock, 10th edn, P. No. 1210.

2.  70.  -  According  to  the  DSM-IV-TR, mental  retardation  is defined  as  significantly subaverage  general  intellectual functioning  resulting  in,  or  associated  with, concurrent impairment  in  adaptive  behavior  and  manifested  during the  developmental  period,  before  the  age  of  18.    General intellectual  functioning  is determined  by  the  use  of standardized  tests  of  intelligence,  and  the  term significantly subaverage  is defined  as  an  IQ  of approximately  70 or  below  or  two  standard  deviations below  the  mean  for  the  particular  test.  Adaptive functioning  can  be  measured  by  using  a  standardized scale,  such as  the  Vineland  Adaptive  Behavior  Scale.  Ref: Synopsis  of  Psychiatry,  Kaplan  and  Sadock,  10th  edn,  P.  NO. 1140.

3.  Retts  disease  -  It has  been  seen  primarily  in  girls,  and case  reports  so  far  indicate  complete  concordance  in monozygotic twins.  During  the  first  5  months  after  birth, infants  have  age-appropriate  motor  skills,  normal  head circumference,  and  normal  growth.    At  6  months  to  2 years  of  age,  however,  these  children  develop  progressive encephalopathy  with a  number  of  characteristic  features. The signs  often  include  the  loss  of  purposeful  hand movements,  which are  replaced  by stereotypic motions, such as  hand-wringing; the  loss  of  previously acquired speech;  psychomotor  retardation; and  ataxia.  Ref: Synopsis  of  Psychiatry,  Kaplan  and  Sadock,  10th  edn,  P.  NO. 1200.

4.  Autism  -  The Modified  Checklist for  Autism  in Toddlers  (M-CHAT;  Robins,  Fein,  &  Barton,  1999).    The M-CHAT  is validated  for  screening  toddlers  between  16 and  30  months  of  age,  to  assess  risk  for  autism  spectrum disorders  (ASD).  Children  who fail  more  than  3 items total  or  2 critical  items  (particularly if  these  scores remain  elevated  after  the  follow-up interview) should  be referred  for  diagnostic  evaluation  by a  specialist trained to evaluate ASD in very young children.

5.  Mental  retardation    An  Act  to  provide  for  the constitution  of  a  body  at  the  national  level  for  the  Welfare of  Persons  with Autism, Cerebral  Palsy, Mental Retardation  and  Multiple  Disabilities.  The  act  provides  for social security and legal guardianship for these children.

6.  Visual  impairment  -  Pervasive  developmental disorders  include  several  that  are  characterized  by impaired  reciprocal  social  interactions,  aberrant  language development,  and  restricted  behavioral  repertoire. Pervasive  developmental  disorders  typically emerge  in young  children  before  the  age  of  3 years.  Other  associated features  include  intellectual  disability (70-75%  of patients),  mood  instability  and  varying  responses  to sensory  stimuli.    Ref:  Synopsis  of  Psychiatry,  Kaplan  and Sadock, 10th edn, P. NO. 1196
