Developmental Language Disorder (DLD) is a language disorder which affects the person who has it from speaking clearly. To put it in a simpler way, it is a disability which is caused by a stroke within the womb.
Throughout Damian's life, DLD had always come under different names, such as, Speech and Language Impairment (SLI), Speech, Language and Communication Needs (SLCN), dysphasia, and many, many more. In the 1990s, when Damian started spreading awareness, it went by the name of dysphasia. Fortunately, now some researchers have come to agree on the name DLD.
With DLD, you won't find two people who have it who are exactly the same, similar to a fingerprint that is the same either.
For more information, please read Damian's book, Finding a Voice which has a large section on What is DLD. Below is some talks that Damian has done and he hopes that he can do a lot more and get paid through it..
