Focused Ultrasound
An early-stage, non-invasive therapeutic technology with the potential to transform the treatment of many medical disorders by using ultrasonic energy to target tissue deep in the body without incisions or radiation.
Focal sensory seizure with cephalic sensation
A focal seizure characterized by a sensation in the head such as light-headedness or headache.
Focal sensory seizure with hot-cold sensations
A focal seizure characterized by sensations of feeling hot and then cold.
Focal sensory vestibular seizure
A focal seizure characterized by symptoms of dizziness, spinning, vertigo or sense of rotation. These seizures involve the parietal cortex, temporo-parieto-occipital junction or parieto-temporal cortex.
Focal sensory gustatory seizure
A focal seizure characterized by taste phenomena including acidic, bitter, salty, sweet, or metallic tastes. These seizures involve the parietal operculum and the insula.
Focal sensory olfactory seizure
A focal seizure characterized by olfactory phenomena – usually an odor, which is often unpleasant. These seizures involve the mesial temporal or orbitofrontal regions.
Focal sensory auditory seizure
A focal seizure characterized by elementary auditory phenomena including buzzing, ringing, drumming or single tones. More complex auditory hallucinations such as voices are considered a focal cognitive seizure. Focal sensory auditory seizures involve auditory cortex in the lateral superior temporal lobe.
Focal sensory visual seizure
A focal seizure characterized by elementary visual hallucinations such as flashing or flickering lights/colours, or other shapes, simple patterns, scotomata, or amaurosis. More complex visual hallucinations such as seeing formed images are considered a focal cognitive seizure. Focal sensory visual seizures arise in the occipital lobe.
Focal somatosensory seizure
A focal seizure characterized by sensory phenomena including tingling, numbness, electric-shock like sensation, pain, sense of movement, or desire to move. These seizures involve the sensorimotor cortex.
Seizure Focus
The center or region of the brain from which seizures begin; used in reference to partial seizures.
