Final answer:
A stroke is diagnosed using diagnostic tests such as CT scans to detect brain bleeding and EEG for recording brain activity. Clinical symptoms are assessed with the FAST mnemonic, emphasizing the importance of swift treatment for better recovery.
Step-by-step explanation:
To diagnose a stroke, neurologists utilize several diagnostic tests. Computerized tomography (CT) scans are frequently used to detect bleeding or tumors in the brain that are indicative of a hemorrhagic stroke. Additionally, an electroencephalography (EEG) may be performed, especially if seizure activity is suspected. This test involves taping electrodes to the scalp to record brain activity and helps locate regions involved in seizures, which parallel stroke symptoms sometimes. Another critical assessment is paying attention to clinical symptoms using the FAST mnemonic - Facial drooping, Arm weakness, Speech difficulties, Time to call emergency services. The rapid response to these symptoms is crucial as timely treatment can greatly influence recovery outcomes.
