Transitory migraine aura symptoms
An attack of migraine is divided into four distinct stages. This website is primarily devoted to the aura phase, i.e. one of two stages that may be present before the actual headache starts.
The aura is the complex of neurological or neuropsychological symptoms, for example
- Visual symptoms, i.e., visual loss, visual hallucinations, visual illusions
- Motor symptoms, e.g. weakness or palsy
- Somatosensory symptoms, e.g. numbness, prickling sensations, etc.
- Body image disturbances, e.g. macro- and microsomatognosia (feeling larger or smaller), out-of-body experiences and felt presences
- Depersonalization and derealization
- Auditory symptoms, e.g. tinnitus (buzzing sounds)
- Gustatory symptoms
- Olfactory symptoms, e.g. hallucinations of odours and smells not actually present
- Speech symptoms
- Language symptoms
- Paramnesias (déjà vu and jamais vu)
- Forced reminiscence
- Time perception disturbances
- Synaesthesia
- Disturbances of dreaming
- Other disturbances of higher cortical functions
The typical symptoms of migraine aura are sensory phenomena that usually occur before the headache phase and propagate in sensory space. Visual auras for example, may propagate through the visual field. This feature is important for an understanding of the pathomechanisms of the migraine aura, the study of which may result in a new classification of visual disturbances (see the sections of the website edited by Markus Dahlem).
