left hemisphere of brain
right hemisphere of brain

If you split the brain down the middle, into two equally-sized parts, they are not the same and do not carry the same functions.

The left side of the brain controls the right side of the body, while the right side of the brain controls the left side of the body.

Each side is responsible for different functions.

General patterns of dysfunction may occur depending on the side of the brain sustaining an injury.

Left Side Traits

The left side of the brain is analytical, logical and literal.

Injuries to the left side of the brain can cause:

Difficulties understanding language and speaking
Depression and Anxiety
Impaired logic and sequencing
Decreased control over right-sided body movements

Right Side Traits

The right side of the brain is creative, imaginative and intuitive.

Injuries to the right side of the brain can cause:

Visual-spatial impairment
Visual and short-term memory deficits
Loss of “the big picture” type of thinking
Altered creativity and music perception
Decreased awareness of deficits
Decreased control over left-sided body movements and inattention to the left side of the body

Parts of the Brain

The brain is also made up of sections called lobes.

Injuries to a brain lobe can also cause patterns of dysfunction.

Frontal Lobe

An injury to the frontal lobes may affect an individual’s ability to control emotions, impulses, and behavior or may cause difficulty recalling events or speaking.

Parietal Lobe

Individuals who have injured their parietal lobes may have trouble with their five primary senses.

Occipital Lobe

An injury to one’s occipital lobes may lead to trouble seeing or perceiving the size and shape of objects.

Temporal Lobe

An injury to the temporal lobes may lead individuals to demonstrate difficulty with communication or memory.


An injury to the cerebellum may affect balance, movement, and coordination.
