• onset of mental disabilities is concentrated <strong>in</strong> childhood and 20-30, result<strong>in</strong>g <strong>in</strong> the<br />
lowest average age of onset. While more analysis is needed, it is assumed that MR is<br />
more focused on the earliest years and mental illness becomes more pronounced <strong>in</strong> young<br />
adulthood.<br />
• <strong>in</strong> contrast, visual disabilities are much more associated <strong>with</strong> age<strong>in</strong>g, <strong>with</strong> easily the<br />
oldest mean age of onset. While hear<strong>in</strong>g disabilities exhibit a more pronounced dual<br />
peak, they are also on average subject <strong>to</strong> later average onset.<br />
• both locomo<strong>to</strong>r and speech disabilities are more concentrated <strong>in</strong> younger ages also,<br />
<strong>with</strong> the highest onset <strong>in</strong> the early years of life <strong>in</strong> both cases, and a more noticeable<br />
second wave of onset for speech disabilities around age 60.<br />

Based on Das (2006), us<strong>in</strong>g NSS 58 th round<br />
3.6. The age profile of onset reflects the differ<strong>in</strong>g structure of causes by disability category.<br />
While aggregate trends <strong>in</strong> disability cause discussed <strong>in</strong> Chapter 1 (i.e. transition from<br />
communicable <strong>to</strong> non-communicable causes, and <strong>in</strong>creas<strong>in</strong>g importance of <strong>in</strong>juries/accidents) are<br />
important, design of appropriate <strong>in</strong>terventions also needs <strong>to</strong> focus on disability-specific profiles of<br />
causes. Critical periods for <strong>in</strong>tervention for locomo<strong>to</strong>r and speech disabilities are particularly <strong>in</strong><br />
early childhood. For mental disabilities, the critical period for MR is also early childhood, while<br />
for mental illness, adolescence and early adulthood are key. For hear<strong>in</strong>g impairments, screen<strong>in</strong>g<br />
throughout life seems important, but especially as people age, and for visual disabilities, the focus<br />
