Psychiatry, Neurology. 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 ...
Magnetic resonance imaging. Hemianopsia, or hemianopia, is a visual field loss on the left or right side of the vertical midline. It can affect one eye but usually affects both eyes. Homonymous hemianopsia(or homonymous hemianopia) is hemianopic visual field loss on the same side of both eyes. Homonymous hemianopsia occurs because the right ...
Frontal lobe disorder. Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [ 5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production. Frontal lobe syndrome can be caused by a range of ...
Pusher syndrome is a clinical disorder following left- or right-sided brain damage, in which patients actively push their weight away from the non-hemiparetic side to the hemiparetic side. This is in contrast to most stroke patients, who typically prefer to bear more weight on their nonhemiparetic side.
Sexual headache is a type of headache that occurs in the skull and neck during sexual activity, including masturbation or orgasm. These headaches are usually benign, but occasionally are caused by intracranial hemorrhage and cerebral infarction, especially if the pain is sudden and severe. [ 1] They may be caused by general exertion, sexual ...
Cerebral hemisphere. Human brain seen from front. The vertebrate cerebrum ( brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral ...
Headache, also known as cephalalgia, is the symptom of pain in the face, head, or neck. It can occur as a migraine, tension-type headache, or cluster headache. [ 1][ 2] There is an increased risk of depression in those with severe headaches. [ 3] Headaches can occur as a result of many conditions. There are a number of different classification ...
The lateralization of brain function (or hemispheric dominance[ 1][ 2] / latralisation [ 3][ 4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.
