Autism spectrum disorder (ASD) is characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. ASD can be associated with intellectual disability, difficulties in motor coordination, attention and health issues such as sleep and gastrointestinal disturbances. Although autism appears to have its roots in very early brain development, the most obvious clinical signs and symptoms of autism tend to emerge between 2 and 3 years of age.
Cerebral palsy (CP) is the most common physical disability of childhood. It occurs in two out 1000 children, appearing on acute, rehab and tertiary health care caseloads worldwide. It is a non-progressive condition whereby an injury occurs in a child’s brain before, during or shortly after birth, and can affect a child’s movement and posture, limiting their everyday activities.
Down syndrome (DS or DNS), also known as trisomy 21, is a genetic disorder caused by the presence of all, or part of a third copy of chromosome 21. It is typically associated with physical growth delays, characteristic facial features, and mild to moderate intellectual disability. The average IQ of a young adult with Down syndrome is 50, equivalent to the mental age of an 8- or 9-year-old child, but this can vary widely.
Epilepsy is a seizure disorder and is characterized by unpredictable seizures. Epilepsy is the fourth most common neurological disorder and affects people of all ages. Many people with epilepsy have more than one type of seizure and may have other symptoms of neurological problems as well. It is also important to note that seizures and epilepsy are not the same. An epileptic seizure is a temporary occurrence of signs and/or symptoms due to abnormal activity in the brain. The abnormal activity is characterized by excessive neuronal activity and/or complex interactions between groups of neurons. With the right tools and therapy, while taking care of emotional health, diet and nutrition, physical activity, sleep, independent living, stress management, social relationship and education, children and adults can improve their outcomes and quality of life.
Children and young people with disabilities constitute about 4-6.5% of the population in many countries (1). In Canada, there are approximately 850,000 children with developmental disabilities. When a baby or preschooler reaches the developmental milestones in a different order or pace, or loses a previously acquired skill, there may be reason to suspect of a developmental disability. When a child has a developmental disability, he/she may experience life-long experiences affecting their mobility, language, learning, socialization, and/or self-care. Early signs and symptoms of childhood disability can vary greatly, however some tools and techniques can help all children with disabilities overcome some of life’s challenges. Prognosis and therapies will vary based on the child’s needs, however early diagnoses and interventions can have a positive impact and significantly improve outcomes for all children with disability.

Global developmental delay (GDD) is a term used to describe a generalized delay in development caused by an alteration in the functioning of the central nervous system and is usually characterized by lower than average intellectual functioning along with significant limitations in at least two other areas of development. Common signs of global developmental delay include delayed acquisition of milestones (e.g., sitting up, crawling, walking), limited reasoning or development of conceptual abilities, poor social skills and judgement, aggressive behaviour as a coping skill, and communication difficulties. Global developmental delay has many causes which sometimes go undetermined. Early intervention and therapy can support a healthy development and the stimulation of the best capacities for children with GDD.
A traumatic brain injury (TBI) varies tremendously in causes, symptoms and outcomes. This may depend on the type of brain injury, the severity, and treatment options. TBI’s and concussions come from a blow to the head, or a violent movement of the cranium, causing a jolt to the brain. They can be caused by a number of reasons such as: violence, sports and recreational activities injuries, transportation accidents, a fall, or assaults. A TBI can be trivial, mild simple, mild complex, moderate and severe, which all have different needs and different possible outcomes. Doctors classify traumatic brain injury as mild, moderate or severe, depending on whether the injury causes unconsciousness, how long unconsciousness lasts and the severity of symptoms. If a TBI is suspected, it is important to speak to a doctor as soon as possible to determine the best course of action.
