JOSE ALVAREZ LA PREGUNTA...

TOURRETE SYMDROME

Tourette syndrome (TS) is named for French doctor Georges Gilles de la Tourette, who first described the condition in 1885. It's thought to be a genetic condition that's inherited in most cases. Experts don't know the exact cause of TS, but some research points to changes in the brain and problems with how nerve cells communicate. A disturbance in the balance of neurotransmitters — chemicals in the brain that carry nerve signals from cell to cell — might play a role.

SYMPTONS

Symptoms of Tourette syndrome, which is not contagious, usually emerge in childhood or the teen years. TS isn't common — only about 3 in every 1,000 people have it, and boys are more likely to be affected.

Alzheimer's

Alzheimer's disease (AD), also known in medical literature as Alzheimer disease, is the most common form of dementia. There is no cure for the disease, which worsens as it progresses, and eventually leads to death. It was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906 and was named after him.Although Alzheimer's disease develops differently for every individual, there are many common symptoms.^[4] Early symptoms are often mistakenly thought to be 'age-related' concerns, or manifestations of stress.^[5] In the early stages, the most common symptom is difficulty in remembering recent events. When AD is suspected, the diagnosis is usually confirmed with tests that evaluate behaviour and thinking abilities, often followed by a brain scan if available.

DISLEXIA

Etymologically the word dyslexia means about language difficulties. In the current meaning refers to reading problems, disorder in reading acquisition.

A first simple definition of dyslexia is telling us that the problem is learning to read which show children whose IQ is normal and there are other physical or psychological problems that may explain these difficulties.

According to some statistics dyslexia affects more or less to 10% or 15% of the school population and adult. It affects equally to boys and girls, but in my practice I have seen many more boys than girls and statistics speak English a 8-1 ratio between the number of boys and girls affected. This may have to do with the fact that he believes that women generally have a greater development in the area of language than men. There is consensus that between 4 and 5% of children have serious problems learning to read, with the consequent difficulty writer.

Given the spread of education to the entire population of a mandatory and priority use of reading and writing as mediators of education, number of children with learning difficulties from this cause is a relevant factor to be considered by the teacher. According to statistics cited above can be expected in each classroom of 25 students have at least one child with this learning difficulty.

A good definition is given M.Thomson "is a serious difficulty with the written form of language, which is independent of any cause intellectual, cultural and emotional. Feature is that the individual acquisitions in the area of reading, writing and spelling, are well below the level expected based on their intelligence and their chronological age. problem is cognitive in nature, affecting those language skills associated with written form, particularly the passage written modality, particularly the passage visual coding to verbal short-term memory, perception of order and sequencing.

There is some confusion in the use of "names" applied to dyslexia. Such qualifiers of "maturational", "evolutionary," "acquired".

In practice we talk about dyslexia when difficulties and symptoms similar or equal to those in dyslexic children who start learning, but these symptoms quickly disappear on their own during learning. The symptoms to which I refer are investments in writing and / or reading, additions, omissions, mirror writing, hesitations, repetitions ...

Aphasia

Aphasia is a disorder caused by damage to the parts of the brain that control language. It can make it hard for you to read, write, and say what you mean to say. It is most common in adults who have had a stroke. Brain tumors, infections, injuries, and dementia can also cause it. The type of problem you have and how bad it is depends on which part of your brain is damaged and how much damage there is.

There are four main types:

Expressive aphasia - you know what you want to say, but you have trouble saying or writing what you mean
Receptive aphasia - you hear the voice or see the print, but you can't make sense of the words
Anomic aphasia - you have trouble using the correct word for objects, places, or events
Global aphasia - you can't speak, understand speech, read, or write

Some people recover from aphasia without treatment. Most, however, need language therapy as soon as possible.
