Illustration of lateral view of the right side of the brain showing the frontal lobe, other lobes of the brain, and the cerebellum: Specialty: Neurology, psychiatry: Symptoms: Tremor, dystonia [1] Causes: Closed head injuries [2] Diagnostic method: Neuropsychological test [3] Treatment: Speech therapy, supportive care [4]
Right hemisphere brain damage (RHD) is the result of injury to the right cerebral hemisphere. [1] The right hemisphere of the brain coordinates tasks for functional communication, which include problem solving, memory, and reasoning. [1] Deficits caused by right hemisphere brain damage vary depending on the location of the damage. [2]
For example, a stroke affecting the right parietal lobe of the brain can lead to neglect for the left side of the visual field, causing a patient with neglect to behave as if the left side of sensory space is nonexistent (although they can still turn left). In an extreme case, a patient with neglect might fail to eat the food on the left half ...
Symptoms of brain injuries can also be influenced by the location of the injury and as a result impairments are specific to the part of the brain affected. Lesion size is correlated with severity, recovery, and comprehension. [4] Brain injuries often create impairment or disability that can vary greatly in severity.
Due to brain or nerve damage, the brain is constantly sending action potentials to the neuromuscular junctions on the affected side of the body. Similar to strokes, damage on the left side of the brain affects the right side of the body and damage on the right side of the brain affects the left side of the body.
Because most research compares those with brain injuries (whether frontal lobe or not) and those without, the scientific community is unsure whether certain memory impairment is specific to frontal lobe injuries, or just traumatic brain injuries in general. There are many factors to consider when examining the effects of a traumatic brain ...
Unequal pupil size is potentially a sign of a serious brain injury. [39] Symptoms are dependent on the type of TBI (diffuse or focal) and the part of the brain that is affected. [40] Unconsciousness tends to last longer for people with injuries on the left side of the brain than for those with injuries on the right. [15]
Callosal syndrome, or split-brain, is an example of a disconnection syndrome from damage to the corpus callosum between the two hemispheres of the brain. Disconnection syndrome can also lead to aphasia, left-sided apraxia, and tactile aphasia, among other symptoms.
