There is an infarct involving the left parieto/temporal/occipital region. Frontotemporal dementia is a group of disorders characterized by the loss of nerve cells in the frontal and temporal lobes of the brain, which causes these lobes to shrink. Temporal lobe epilepsy (TLE) is a chronic disorder of the nervous system characterized by recurrent, unprovoked focal seizures that originate in the temporal lobe of the brain and last about one or two minutes. Temporal lobe seizures are sometimes called focal seizures with impaired awareness. Thalamic strokes are typically medically managed and have a wide variety of prognoses depending on the location, size and nature of the infarct. The regions of the brain each have specific functions, including physical movement, sensation, speech, thinking skills, emotions—just about everything the body does. Fever. In subsequent months, the patient complained of fatigue, quadrantanopsia, memory problems, and topographical disorientation. If there is an infarction in the temporal lobe involving the Meyer loop or infracalcarine, it may present with superior quadrantanopia. Dr. Alan Ali answered. Side Effects of Stroke in the Temporal Lobe. A stroke is a medical emergency that can occur when the blood supply to part of the brain is cut off or when a blood vessel in the brain bursts and releases blood into the brain tissue. The upper surface of the temporal lobe is delimited from the frontal and parietal lobes by the sylvian fissure. 9, Loss of upper monocular crescent bundle (contralateral inferior monocular crescentic defect): tumor, infarctionor[dartmouth.edu] Memory impairment Infarctionof the medial temporallobe, fornices, or medial thalamic nuclei may result in permanent anterograde amnesia. Jaw pain that may become worse after chewing. 3. Temporal lobe seizures are treated with medication.

The dominant temporal lobe, which is the left side in most people, is involved in understanding language and learning and remembering verbal information. It results from dysfunction of the language centers in the cerebral cortex and basal ganglia or of the white matter pathways that connect them. There are eight principal symptoms of temporal lobe damage:Disturbance of auditory sensation and perception.Disturbance of selective attention of auditory and visual input.Disorders of visual perception.Impaired organisation and categorisation of verbal material.Disturbance of language comprehension.Impaired long-term memory.Altered personality and affective behaviour.Altered sexual behaviour. Autopsy showed bilateral damage of the medial temporal lobe… The internal carotid arteries were involved in 4 patients and the vertebrobasilar arteries in 3, with bilateral vertebral artery occlusion in 1.

Q: “Adding damage to specific regions of the cerebral cortex, such as through a stroke, can result in specific losses of function. The limbic system’s network of connected structures that are linked within the CNS work together and affect a wide range of behaviors. The temporal lobe is the second largest lobe, after the larger frontal lobe, accounting 22% of the total neocortical volume 6.. A stroke in the temporal lobe can affect many important functions like memory, language, and emotion. 1. What signs and symptoms would a patient exhibit if he or she had a frontal lobe ischemic stroke? Therefore, visual field loss (Markus et al., 2013) and visual perception changes are typical after OL strokes (Mesulam, 2000). Blood vessels in the head known as the temporal arteries are affected by temporal arteritis. The tPA caused a bleed in my left temporal lobe, where the stroke was occurring. Aphasia is language dysfunction that may involve impaired comprehension or expression of words or nonverbal equivalents of words. Temporal lobe epilepsy is the most common form of focal epilepsy. A frontal lobe stroke can produce a variety of symptoms, some of which are more clearly related to the stroke (weakness) and some of which can be confused with depression or dementia.
