Autism spectrum disorder (ASD) and autism are both terms for a group of disorders of brain development. With the May 2013 publication of the DSM-5 diagnostic manual, all autism disorders were merged into one diagnosis of ASD. Previously, they were recognized as distinct subtypes, including autistic disorder, childhood disintegrative disorder, pervasive developmental disorder-not otherwise specified (PDD-NOS) and Asperger syndrome. Autism is a neurodevelopmental disorder that results from maturation-related changes in various systems of the brain. Autism is highly heritable, but the cause includes both environmental factors and genetic susceptibility. In rare cases, autism is strongly associated with agents that cause birth defects.  Stem cell therapy is a novel and effective approach to treating autism and is based on the unique ability of stem cells to influence metabolism, immune system and restore damaged cells and tissues.
WHAT ARE THE SYMPTOMS?
Autism spectrum disorder impacts how a child perceives and socializes with others, causing problems in crucial areas of development — social interaction, communication and behavior. The severity of symptoms varies greatly, but all people with autism have some core symptoms in the areas of :
- Social interactions and relationships. Difficulty developing nonverbal communication skills. Lack of empathy and sharing enjoyment or achievements with others.
- Verbal and nonverbal communication. Delay or lack of learning to talk. Difficulty starting and engaging in conversation.
- Limited interests in activities or play. Preoccupation with certain topics. A need for sameness and routines.
No cure currently exists for autism spectrum disorder. The goal of treatment is to maximize a child’s ability to function by reducing ASD symptoms and supporting development. Treatment options may include :
- Behavior and communication therapies
- Educational therapies
- Family therapies
