What is epileptic aphasia?
What is epileptic aphasia?
The epilepsy-aphasia spectrum is a group of conditions that have overlapping signs and symptoms. A key feature of these conditions is impairment of language skills (aphasia). The language problems can affect speaking, reading, and writing.
Is aphasia related to epilepsy?
Different types of aphasia may be caused by lesions in different regions of the brain (2). Ictal or postictal aphasia, also known as epileptic aphasia, occurs following epileptic seizures and is a common event (3). Aphasia may resolved with the end of epilepsy.
What is ictal aphasia?
Ictal aphasia: an unusual presentation of temporal lobe seizures.
Can epilepsy cause speech problems?
Some types of Epilepsy are associated with speech and language difficulties. Epilepsy can result in a temporary loss of function in one or more areas of the brain. If the areas of the brain responsible for understanding and communication are affected, speech and language difficulties can occur.
What are the types of aphasia?
Types of Aphasia
- Global Aphasia. Global aphasia is the most severe type of aphasia.
- Broca’s Aphasia. Broca’s aphasia is also called non-fluent or expressive aphasia.
- Mixed Non-Fluent Aphasia.
- Wernicke’s Aphasia.
- Anomic Aphasia.
What is meant by aphasia?
Aphasia is a disorder that results from damage to portions of the brain that are responsible for language. For most people, these areas are on the left side of the brain.
What is ictal speech?
Ictal vocalizations have been defined as an audible sound that carries no speech quality. 1. They occur in 40% to 60% of patients with frontal lobe epilepsy and often present as repetitive nonspeech sounds, such as the grunting noted at the onset of our patient’s seizures.
How long does Postictal aphasia last?
The aphasia improved slowly 7 to 10 days after her convulsion as the intracranial EEG discharges gradually subsided. Comprehension and naming deficits were the last to improve.
Can epilepsy cause speech problems in adults?
Adults with epilepsy often complain of difficulties with language (especially difficulties in coming up with words), but for most of them the problems are not severe enough to be classified as a bona fide aphasia.
What are the 6 types of aphasia?
Types of Aphasia
- Global Aphasia. Global aphasia is the most severe type of aphasia.
- Broca’s Aphasia. Broca’s aphasia is also called non-fluent or expressive aphasia.
- Mixed Non-Fluent Aphasia.
- Wernicke’s Aphasia.
- Anomic Aphasia.
- Primary Progressive Aphasia (PPA)
What are the 4 types of aphasia?
The most common types of aphasia are: Broca’s aphasia. Wernicke’s aphasia. Anomic aphasia….Primary progressive aphasia (PPA)
- Read.
- Write.
- Speak.
- Understand what other people are saying.
What causes a postictal state?
The postictal state is thought to occur due to changes that take place in the brain following a seizure. These changes can be in electrophysiology (e.g., “neural exhaustion”), cerebral blood flow, and neurotransmitter systems and receptors (Fisher & Schachter, 2000; Gursahani & Gupta, 2012).
What is an ictal cry?
Ictal crying is a rare finding among patients evaluated at EMUs. The most common underlying etiology for ictal crying is PNES. However, ictal crying is not a specific or pathognomonic sign for PNES. Epileptic ictal crying is a rare type of partial seizure in patients with focal epilepsy.
Can a seizure cause temporary aphasia?
Sometimes temporary episodes of aphasia can occur. These can be due to migraines, seizures or a transient ischemic attack (TIA). A TIA occurs when blood flow is temporarily blocked to an area of the brain.
Can focal seizure cause aphasia?
Focal cognitive seizures can be further described using the following descriptors: Focal cognitive seizure with expressive dysphasia / aphasia – the onset of inability to speak, in a patient who reports being aware of what they wished to say but being unable to express this.
What are the 8 types of aphasia?
The Most Common Types of Aphasia
- Anomic Aphasia.
- Broca’s Aphasia.
- Conduction Aphasia.
- Global Aphasia.
- Primary Progressive Aphasia.
- Mixed Transcortical Aphasia.
- Transcortical Motor Aphasia.
- Transcortical Sensory Aphasia.
What are the 2 types of aphasia?
There are two broad categories of aphasia: fluent and nonfluent, and there are several types within these groups. Damage to the temporal lobe of the brain may result in Wernicke’s aphasia (see figure), the most common type of fluent aphasia.
What is ictal and interictal?
Epileptiform EEG activity has been categorized as ictal, meaning during a seizure, postictal, meaning after a seizure and interictal, meaning between seizures.
What is acquired epileptic aphasia?
Acquired epileptic aphasia is a progressive condition that mainly occurs in children of about 6 years of age and is characterized by gradual loss of expressive and receptive language ability. Most children affected by Acquired epileptic aphasia also experience epileptic seizures at night due to paroxysmal electroencephalographic changes.
What is epilepsy-aphasia spectrum?
The epilepsy-aphasia spectrum is a group of conditions that have overlapping signs and symptoms. A key feature of these conditions is impairment of language skills (aphasia). The language problems can affect speaking, reading, and writing.
What is aphasia?
Aphasia: repetition of words/phrases good; may repeat questions rather than answering them (“echolalia”) Classification of Aphasia This figure describes various aphasia types, using a classification system based on characteristics of verbal expression (nonfluent or fluent; Davis, 2007; Goodglass & Kaplan, 1972).
How is epileptic aphasia diagnosed?
Diagnosis of Acquired Epileptic Aphasia. Positron Emission Tomography: In one or both temporal lobes, Fluorodeoxyglucose Positron Emission Tomography or FDG-PET imaging shows reduced metabolism. Single-photon emission computed tomography or SPECT of the brain shows reduced perfusion of the left temporal lobe.
