Selective mutism. In selective mutism, a child is able to speak in some situations but unable to speak (is mute) in others.
Obsessive compulsive disorder (OCD). Some children with obsessive-compulsive disorder, like those with autism, have unusual interests and repetitive behaviors. But unlike children with autism, children with OCD are able to develop social and communication skills.
Reactive attachment disorder. In this disorder, there is usually a history of severe neglect. Language and social skills usually begin to develop after a child is given love and attention.
If you notice your child losing their language skills at a young age this is cause for you to talk to your pediatrician. Autism is still very difficult to diagnose but the sooner the better.
