What are the causes of aphasia PDF?

Causes

• Stroke – In stroke, the brain is deprived of oxygen and vital nutrients, which causes brain tissue to die off.
• Severe head injury, such as injury resulting from a road traffic accident or serious fall.
• A brain tumor.
• Brain infections such as meningitis or encephalitis.

How is anomic aphasia diagnosed?

Anomic aphasia test Imaging tests like an MRI look for brain damage. Anomic aphasia isn’t caused by damage to a consistent part of the left hemisphere so diagnosis is difficult through brain imagining alone. Verbal tests aim to find out if the problem is with language comprehension or production.

What are the types of aphasia?

Types of Aphasia

• Global Aphasia. Global aphasia is the most severe type of aphasia.
• Broca’s Aphasia. Broca’s aphasia is also called non-fluent or expressive aphasia.
• Mixed Non-Fluent Aphasia.
• Wernicke’s Aphasia.
• Anomic Aphasia.

Can aphasia lead to death?

The condition begins in middle age with only language difficulties, but memory, visual processing, and personality will become affected in the advanced stages of the disease. This case study describes a 70-year-old man who was diagnosed with PPA and it progressed to dementia and death.

Can stress and anxiety cause aphasia?

People with PPA can experience many different types of language symptoms. In many instances, the person with PPA may be the first to note that something is wrong and the complaints may initially be attributed to stress or anxiety.

Can medications cause anomic aphasia?

So far, several medications have been reported to cause aphasia, including: ipilimumab; immunomodulatory drugs (thalidomide, lenalidomide, pomalidomide); lamotrigine; vigabatrin; sulfasalazine; cyclosporine A; ifosfamide; phenylpropanolamine; naftidrofuryl oxalate; and some contrast mediums (Table 1).

What neurological disease causes aphasia?

Although it is primarily seen in individuals who have suffered a stroke, aphasia can also result from a brain tumor, infection, inflammation, head injury, or dementia that affect language-associated regions of the brain. It is estimated that about 1 million people in the United States today suffer from aphasia.

What part of the brain is damaged in aphasia?

Aphasia is caused by damage to the language-dominant side of the brain, usually the left side, and may be brought on by: Stroke.

Does aphasia turn into dementia?

There is a specific type of aphasia that is caused by dementia – Primary Progressive Aphasia (PPA). PPA is the result of brain tissue degenerating, specifically the brain tissue in the language regions of the brain. PPA is most closely associated with Frontotemporal Dementia (FTD).

What is the life expectancy of a person with aphasia?

Outlook / Prognosis Primary progressive aphasia worsens over time. Many people with PPA eventually lose their language skills over many years, limiting their ability to communicate. Most people who have the condition live up to 12 years after their initial diagnosis.

Does aphasia lead to dementia?

Aphasia symptoms associated with dementia People with the most common types of dementia, such as Alzheimer’s disease and vascular dementia, usually have a mild form of aphasia. This often involves problems finding words and can affect names, even of people they know well.

What disease can cause aphasia?

Aphasia is most often caused by stroke. However, any type of brain damage can cause aphasia. This includes brain tumors, traumatic brain injury, and brain disorders that get worse over time.

Can high blood pressure cause aphasia?

People who have risk factors for stroke (high blood pressure, diabetes, smoking or high cholesterol) are most likely to acquire aphasia.

What virus causes aphasia?

However, because Herpes simplex virus (HSV) encephalitis infection usually affects the frontal and temporal lobes, subcortical structures and hippocampal tissue, the link between aphasia and HSV encephalitis is investigated in this article, based on the neuro-anatomical site of brain damage caused by such infection.

Does aphasia worsen with age?

Symptoms begin gradually, often before age 65, and worsen over time. People with primary progressive aphasia can lose the ability to speak and write and, eventually, to understand written or spoken language.

Does aphasia lead to death?

That’s because aphasia and dementia are often hard to diagnose in terms of pinpointing an exact time of projected death. Doctors simply can’t predict with any certainty when an aphasia patient has only six months left to live. As a result, they don’t often make it into hospice care at all, or too late.
