A

Alternative Augmentative Communication

Alternative Augmentative Communication (AAC) is a form of alternate communication offered to individuals who do not have the capacity to use spoken word or who need more support with their communication. This can be through the use of high tech or low tech aids.

Acquired disorders

Acquired disorders are disorders which are not acquired at birth, therefore acquired later on in life. They can occur at any time and usually have an organic cause.

Attention Deficit Hyperactivity Disorder (ADHD)

Attention Deficit Hyperactivity Disorder (ADHD) is a disorder which affects a child's ability to attend for a significant amount of time and can vary in severity. ADHD is a condition that will need to be diagnosed by an appropriate medical professional.

Agnosia is a disorder which affects understanding of speech and object perception. This can be either congenital or acquired and can range from mild to severe. Different variations can occur and will depend upon the individual.

Alzheimer's disease

Alzheimer's disease is a type of dementia, currently the cause is unknown. It occurs when neurons are lost in the brain. Alzheimer's sufferers will have a gradual loss of memory. Short term memory is affected initially, leading to long term memory being affected during the later stages.

Ankyloglossus

Ankyloglossus is the medical term for a tongue tie. A tongue tie occurs when tongue movement is restricted due to the lingual frenulum being attached all the way along the underside of the tongue. Surgery is possible in children or speech and language therapy strategies can be given to compensate for articulation difficulties.

Aphasia

Aphasia occurs after trauma has occurred in the left hemisphere of the brain which then affects the language centre. This results in clients having difficulty with either expressive language, receptive language or both. Depending upon the individual aphasia can range from mild to severe, treatment will vary accordingly depending upon which part of the brain has been affected. The three main types of aphasia are; global, Wernicke's and Broca's aphasia.

  • Broca's aphasia - Broca's aphasia occurs when there is damage in the Broca's area in the brain. This will lead to non-fluent speech which contains reduced grammar and vocabulary, especially with function words.
  • Wernicke's aphasia - Wernicke's aphasia occurs when there is damage to the wernicke's area of the brain. Damage in this area, leads to difficulties with verbal comprehension. This means that their speech is fluent; however they will not necessarily have the correct vocab for what they are trying to say. This leads to confusion and frustration for the client, friends and family.
  • Global aphasia - Global aphasia occurs when there is a considerable amount of damage to the brain. This results in all aspects of language being impaired. Severity will depend upon the individual.

Client centred therapy

Client centred therapy is an approach taken to ensure the goals and aspirations of clients are always at the centre of therapy decisions which are made. This also means clients will have a chance to explain what they feel would be most beneficial for them to work on.
