Types of Disabilities
In our daily lives, we may encounter individuals living with various disabilities.
To interact with awareness and care, it is essential to understand the different types of disabilities, as we might not realize that a certain condition is classified as one.
Disabilities include visual impairment, hearing impairment, intellectual disability, physical and motor disability, learning disabilities, speech and language disorders, behavioral and emotional disorders, autism, multiple and dual disabilities, and others that require specialized care. Each disability varies in severity from person to person, as well as in its treatability.
1. Physical (Motor) Disability
Physical disability is divided into five main categories:
- First: Cerebral Palsy (CP): A neurological disorder caused by brain damage that results in paralysis. It may affect all four limbs (quadriplegia), only the lower limbs (paraplegia), or one side of the body (hemiplegia), leading to a loss of control over voluntary movements.
- Second: Progressive Muscular Dystrophy: A genetic disease that begins by affecting the voluntary muscles in the four limbs and progressively impacts involuntary muscles.
- Third: Spina Bifida: This occurs when parts of the spinal cord protrude through an opening in the vertebrae, causing severe damage to vital cells and leading to a total or partial loss of essential functions.
- Fourth: Congenital Deformities: Various physical abnormalities caused by genetic or non-genetic factors during abnormal pregnancy. These affect joints or bones, appearing as underdeveloped limbs or skeletal malformations.
- Fifth: Other Diagnoses: This includes various conditions such as polio, osteoporosis, endocrine disorders, spinal cord diseases, chronic peripheral nerve diseases, and chronic vascular diseases.
2. Intellectual Disability
Intellectual disability is defined as a state of arrested or incomplete mental development. It is characterized by impaired skills during the developmental cycle, affecting overall intelligence, including cognitive, linguistic, motor, and social abilities. It may occur with or without other psychological or physical disorders.
One of the most well-known types is Down Syndrome, a congenital disorder caused by an extra chromosome in the body’s cells; the probability of its occurrence increases with maternal age.
3. Visual Impairment
Visual impairment ranges from total blindness to partial sight. Accordingly, there are two types:
- The Blind: Those whose condition requires the use of the Braille system.
- The Visually Impaired: Those who can see with the help of visual aids.
4. Hearing Impairment
Hearing impairment is a general term covering a wide spectrum of hearing loss, ranging from total deafness to severe or mild loss. Its signs can be visible or hidden. Hidden impairment may lead to life challenges for a child without the cause being identified, such as academic failure. A child might be unfairly labeled as “unintelligent” due to their lack of interaction. Hearing impairment is often associated with other conditions, such as Down Syndrome, Cerebral Palsy, intellectual disability, Autism, ADHD, cleft palate, and cleft lip.
