That being said, there is a significant and growing body of evidence which indicates that autism[0], ADHD[1], and OCD[2] are being overdiagnosed, or diagnosed without proper clinical rigour.
How can those who are suffering from these disorders hope to get the best quality help if there are so many challenges around proper diagnosis?

People who actually have OCD are being misdiagnosed with other more specific disorders due to a poor understanding of the heterogeneity of the condition.
So by and far it's diagnosis is actually made very late, but I guess over time it'll become trendy aswell.
