What happens when the left temporal lobe is damaged?
Left temporal lesions disturb recognition of words. Right temporal damage can cause a loss of inhibition of talking. The temporal lobes are highly associated with memory skills. Left temporal lesions result in impaired memory for verbal material.
Is dry mouth a symptom of seizures?
What are the symptoms? Although dissociative seizures start as an emotional reaction, they cause a physical effect. Features of the seizure can include palpitations (being able to feel your heart beat), sweating, a dry mouth, and hyperventilation (over-breathing).
How does temporal lobe get damaged?
The most common cause of temporal lobe lesions is a CVE. Space-occupying lesions may be primary brain tumours – benign (such as meningioma) or malignant. They may also be secondary tumours or metastatic carcinoma, most often from lung cancer or breast cancer.
What is hippocampal sclerosis?
Hippocampal sclerosis is the commonest cause of drug-resistant epilepsy in adults, and is associated with alterations to structures and networks beyond the hippocampus.In addition to being a cause of epilepsy, the hippocampus is vulnerable to damage from seizure activity.
What is Geschwind syndrome?
A characteristic personality syndrome consisting of circumstantiality (excessive verbal output, stickiness, hypergraphia), altered sexuality (usually hyposexuality), and intensified mental life (deepened cognitive and emotional responses) is present in some epilepsy patients.
What is mesial temporal lobe epilepsy?
Mesial temporal lobe epilepsy (MTLE) involves the medial or internal structures of the temporal lobe. Seizures often begin in a structure of the brain called the hippocampus or surrounding area. MTLE accounts for almost 80% of all temporal lobe seizures.
What causes temporal lobe scarring?
Brain damage from traumatic injury, infection, a brain tumor, a lack of oxygen to the brain, or uncontrolled seizures is thought to cause the scar tissue to form, particularly in the hippocampus, a region of the temporal lobe.
What are the symptoms of temporal lobe lesions?
The following symptoms are specific to lesions of the temporal lobe: 1 A change in behavior and emotions. 2 Disruption in the sense of smell, taste, and hearing. 3 Language and speech disorders. 4 Problems with field of vision. 5 Forgetfulness and the inability to focus.
Can a brain tumour cause damage to the temporal lobe?
Brain tumours may also affect the temporal lobe of the brain. A serious head injury or a surgical operation to remove a brain tumour may may also cause damage to the temporal lobe. Progressive worsening of language can be part of a type of dementia called frontotemporal dementia.
What causes progressive worsening of language in the temporal lobe?
Progressive worsening of language can be part of a type of dementia called frontotemporal dementia. The temporal lobe can be affected by an infection of the brain (encephalitis), especially encephalitis due to herpes simplex virus.
Where is the temporal lobe located in the brain?
Temporal lobe – located on each side of the brain at ear level, is important for hearing, memory and speech. Parietal lobe – at the center of the brain, is where sensory information like heat, pressure and pain is received and interpreted. Occipital lobe – found at the back of the brain, is primarily responsible for vision.
