Dyslexia is a learning disability where the cognitive ability to read, write and understand language is affected. No official definition has ever been reached for it because it encompasses a number of different deficits and difficulties rather than just one condition.
Some of these other deficits are as follows:
- Aphasia - Normally brain damage occuring in this case where the person in question will suffer neurologically based speech disorders, which can develop into Alexia (acquired dyslexia)
- Attention Deficit Hyperactivity Disorder - Otherwise known as ADHD, it is a disorder that occurs in 12 - 24% of people with Dyslexia.
- Auditory Processing Disorder - A disorder that affects ones ability to process information that they hear. A lot of people with dyslexia suffer from this too, leading to problems with their auditory memory.
- Developmental Dyspraxia - A neurological condition that is characterized by difficulty with doing things that involve balance, fine motor control, kinesthetic coordination, difficulty using sounds in speech, problems with short term memory and organisation.
- Scotopic Sensitivity Syndrome - A term used to describe sensitivity to some wavelengths of light that seem to interfere with visual processing.
- Dyscalculia - A neurological condition that presents itself to be a problem with a basic understanding of numbers, quantity and a difficulty to retrieving rote mathematic facts. Usually people with this disorder can understand very complex mathematical concepts and principles but have difficulty grasping the basics, such as addition and subtraction of numbers.
- Attention Deficit Disorder - A disorder affecting the attention span of the person affected, this is very common in people with Dyslexia.
- Cluttering - A speech fluency disorder including both the rate and rhythm of speech, resulting in impaired speech intelligibility.
Many dyslexics will have at least two of these other deficits, if not more. The term Dyslexia came from the greek 'Dys' meaning Difficulty and 'Lexis' meaning Language.
A lot of people don't know that Dyslexia can affect a persons ability to play a musical instrument, their concept of time when doing a given task and even hinder their ability to walk in a straight line. One of the myths of Dyslexia is that when reading they write words backwards and mix letters up, this only occurs in a fraction of Dyslexic people, not all of them.
The difference between Dyslexia and other learning disabilities is that there is no set level, there are different types of dyslexia and unlike other learning difficulties Dyslexic people have their good days and bad days, some days they'll be better because of their approach to the task. It can be worsened by tiredness, stress, anxiety and nervousness. Such as in cluttering, if someone is nervous talking in front of others and they notice that others have noticed their mistakes during speech their stress levels will increase and it will worsen as they continue to speak until they start to panic.
There is no Cure for Dyslexia, it can be helped with appropriate educational assistance, early intervention is helpful and in about 50% of cases, crucial. One of the best approaches to helping a dyslexic is to acknowledge that the objective in helping improve a dyslexics reading is not to 'read like a non-dyslexic does', but to find a different method of extracting the information in the text being read.
