Aphasia is not caused by damage to the brain that results in motor or sensory deficits, which produces abnormal speech; that is, aphasia is not related to the mechanics of speech but rather the individuals language cognition (although a person can have both problems, as an example, if they have a haemorrhage that damaged a large area of the brain). An individuals language is the socially shared set of rules, as well as the thought processes that go behind communication (as it affects both verbal and nonverbal language). It is not a result of a more peripheral motor or sensory difficulty, such as paralysis affecting the speech muscles or a general hearing impairment. Neurodevelopmental forms of auditory processing disorder are differentiable from aphasia in that aphasia is by definition caused by acquired brain injury, but acquired epileptic aphasia has been viewed as a form of APD. Prevalence
Aphasia affects about two million people in the U.S. and 250,000 people in Great Britain. Nearly 180,000 people acquire the disorder every year in the U.S., 170,000 due to stroke. Any person of any age can develop aphasia, given that it is often caused by a traumatic injury. However, people who are middle aged and older are the most likely to acquire aphasia, as the other etiologies are more likely at older ages. For example, approximately 75% of all strokes occur in individuals over the age of 65.
Ataque de nervios (Spanish pronunciation: [aˈtake ðe ˈneɾβjos], also known as "Puerto Rican syndrome") is a psychological syndrome mostly associated, in the United States, with Spanish-speaking people from the Caribbean, although commonly identified among all Iberian-descended cultures. Ataque de nervios translates into English as "attack of nerves", although it is used in its common cultural form to refer to a specific pattern of symptoms, rather than being a general term for feeling nervous. The condition appears in Appendix I of the revised fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) as a culture-bound syndrome. Classification
Despite comparisons to panic attacks, investigators have identified ataque de nervios as a separate syndrome with measured differences in anxiety sensitivity, and types of attacks. Marlene Steinberg, an Associate Research Scientist at Yale University stated that because it is similar to Multiple Personality Disorder, some Hispanics may be misdiagnosed with an ataque de nervios syndrome instead. Symptoms
Reported aspects of the syndrome include uncontrollable screaming or shouting, crying, trembling, sensations of heat rising in the chest and head, dissociative experiences, and verbal or physical aggression. The reaction is usually associated with a stressful event relating to the family, although it is not specifically defined as arising from such occurrences. History
Ataque de nervios was first mentioned after studies were conducted by US psychiatrists who focused on healthcare for Hispanic populations, particularly individuals who were Puerto Rican and living in the United States . See also
