Right hemisphere brain damage Patients with right hemisphere brain damage most commonly have difficulties with attention, perception, learning, memory, recognition and expression of emotion, and neglect.[3] Other frequently occurring, though slightly less common, deficits include reasoning and problem solving, awareness, and orientation.[3] It is also common for patients with right hemisphere damage to have a flat affect, lack of emotional expression, while speaking. Additionally, these patients commonly have difficulty recognizing other people's emotions when expressed through facial expressions and tone of voice.[2] Although these deficits alone may complicate therapy, the patient may also exhibit anosognosia, or ignorance of his or her impairments.[4][5] Due to possible anosognosia, it is common for patients to not become frustrated or upset when they are unable to complete tasks they were previously able to complete.[6]
