Neurogenic Stuttering: This is a kind of disorder that affects the fluency of how an individual speaks. The person will have difficulty in creating speech in a fashion that is smooth and normal. Individuals with disorders of fluency can have speech that is fragmented or halting with interruptions that are frequent and problems in the production of words without struggling and a lot of effort. Neurogenic stuttering normally appear after some kind of injury or problem to the CNS or “central nervous system”, for instance the spinal cord and the brain which includes the cortex, subcortex, cerebellar as well as the regions of the neural pathway. These diseases and injuries include: cerebrovascular accident or stroke with or without aphasia, ischemic attacks which are temporary obstruction of the flow of blood in the brain, head trauma, cysts, tumors and other neoplasm, degenerative diseases such as multiple sclerosis or Parkinson’s disease.

Other diseases can include meningitis, AIDS as well as Guillain-Barre syndrome and side-effects which are drug related or related to a certain medication.

In the majority of cases, the disease or injury causing the stuttering may be identified. In a small number of cases, the individual might only show evidence of a form of speech disruption with no evidence that is clear of any damage neurologically.

Normally individuals who experience stuttering that is neurogenic have had a past history of normal speech before the disease or the injury. In a few number of cases, neurogenic stuttering can happen in those individuals who have experienced what is known as “developmental stuttering” that may occur at any age; but, it appears most often in adulthood and the highest numbers are in the geriatric community. This is a quite different profile from stuttering that is developmental and is not typically seen as a result of damage to the brain and which most of the time appears in early childhood with those children between two and five years of age.
