FCD

FCD is an acronym that can refer to different concepts depending on the context. The most widely used meaning in medicine is focal cortical dysplasia, a group of developmental abnormalities of the cerebral cortex that can cause epilepsy.

In neurology and radiology, focal cortical dysplasia (FCD) describes a spectrum of cortical malformations. It is classified by the International League Against Epilepsy into subtypes I, II, and III, with Type II further divided into IIa and IIb. FCD often presents with pharmacoresistant seizures, particularly in children and young adults. Magnetic resonance imaging may show focal cortical thickening, blurring of the gray–white matter junction, and the transmantle sign, especially in Type II. Treatment for suitable candidates frequently involves surgical resection or disconnection to achieve seizure control, and prognosis improves with more complete removal of the affected tissue.

In finance, FCD can denote foreign currency deposits, referring to bank deposits denominated in currencies other than the depositor’s local currency. Such accounts may offer different interest rates and carry exchange-rate risk. Availability, regulatory treatment, and protection schemes for FCDs vary by country and financial institution.

Beyond these uses, FCD may appear in other domains as an abbreviation for organizations, projects, or technical terms, underscoring that its meaning is highly context-dependent. If you have a specific field in mind, a more precise article can be provided.
