Dyslexia was the first general term used to describe various learning problems. Because of this, we might call dyslexia the Mother of Learning Disabilities. Now over seventy names are used to describe its various aspects, the most recognised terms being Attention Deficit Disorder (ADD) and Attention Deficit Hyperactive Disorder (ADHD).

THE CLASSICAL WESTERN DEFINITION OF DYSLEXIA:

A disability, of constitutional origin, in reading and spelling, in a person of normal intelligence, as a result of auditory and visual perceptual disturbance. These disturbances must be of a consistent nature.

THE DAVIS DEFINITION OF DYSLEXIA:

• Dyslexia is a type of disorientation caused by natural cognitive ability which can replace normal sensory perceptions with conceptualisations.
  Conceptualisations: here, it simply means, that what comes into the eyes and ears is, somehow, NOT consistent or accurate to reality.
• Dyslexia is a product of thought and a special way of reacting to the feeling of confusion regarding symbols.

WHAT DYSLEXIA IS NOT

Dyslexia is not a medical, neurological or psychological problem. It is not the result of a genetic flaw, physical abnormality, brain injury or nerve damage. It is not caused by a malformation of the brain, inner ear or eyes. It is not limited to reversals of letters and words- that is a common misconception.
