Strokes affect each individual differently depending on the extent of the damage and the area of the brain affected. Damage to one of the language areas of the brain will often result in aphasia. Aphasia is a communication impairment that impacts identity and relationships because of difficulties speaking, understanding, reading, and writing (Kagan & Simmons-Mackie, 2013).
The left hemisphere of the brain controls the right side of the body and the right hemisphere of the brain controls the left side of the body. Damage to the different hemispheres of the brain will result in different impairments. Based on location of the stroke, the following may be affected.
Left Hemisphere:
- Speaking
- Reading
- Writing
- Listening
- Grammar
- Number/Math skills
- Computation skills
- Analyzing information
- Reasoning
- Logic
- Sequential thinking
- Time awareness
Right Hemisphere:
- Organizing information
- Abstract meaning
- Context
- Spatial relationships
- Visual information
- Face recognition
- Intuition
- Emotion
- Imagination
- Detecting motion
- Music and art awareness
Communication Challenges
Aphasia can affect both expressive and receptive language as well as cognition. It is important to note however, that aphasia does not affect intellect. Below is a list of communication challenges a person with aphasia may experience.
Expressive Language
- Difficulty with word finding
- Slurred or unintelligible speech
- Difficulty writing
- Trouble using numbers or doing math
Receptive Language
- Trouble understanding spoken language
- Trouble following directions
- Difficulty reading
Cognitive Problems
- Difficulty maintaining attention
- Memory loss
- Trouble with reasoning or problem solving
- Difficulty making judgments
- Disorganization
- Disorientation
- Slow processing speed
In addition to aphasia, a stroke survivor may be diagnosed with apraxia of speech and/or dysarthria.
Apraxia of Speech
Difficulty initiating and executing voluntary movement patterns necessary to produce speech when there is no paralysis or weakness of speech muscles. Apraxia of speech is characterized by:
- Difficulty producing the desired speech sound
- Difficulty using the correct rhythm and rate of speaking
Dysarthria
A speech disorder caused by muscle weakness. It can make talking clearly very hard. Dysarthria is characterized by:
- Slurred or mumbled speech
- Effortful/slow speech
- Limited movement in tongue, lips, and jaw
- Robotic or choppy sounding speech
- Hoarseness or breathiness
