Researchers have called this subtype sign anomia.
The symptoms of early dementia usually include memory difficulty, but can also include some word-finding problems (anomia) and problems with planning and organizational skills (executive function).
Therefore, when sensory information is unable to reach the hemisphere that is language-dominant (typically the left hemisphere in most individuals), the result is anomia.
Some of the patients received a drug known to help relieve symptoms of anomia (levodopa) while others received a placebo.
Some patients with word selection anomia may exhibit selective impairment in naming particular types of objects, such as animals or colors.
Additionally, bilingual patients typically experience anomia to a greater degree in just one of their fluent languages.
Clinical signs include fluent aphasia, anomia, impaired comprehension of word meaning, and associative visual agnosia (inability to match semantically related pictures or objects).
Stroke, head trauma and brain tumors can cause anomia.
