Embodiment Construction

[0017] As previously mentioned, TIA episodes impose problems with blood flow to the affected brain or nervous tissue, TIA episodes are recognized risk factors for stroke or vascular dementia and are associated with nonvascular dementias such as Alzheimer's disease. silent disease) associated. For these and other reasons, early detection of TIA is beneficial.

[0018] Because TIA symptoms are transient, diagnosing a TIA can be difficult more than 24 hours or so after its onset. Furthermore, if a TIA episode occurs when the victim is alone, no one observes the symptoms and the victim can be left in an impaired cognitive state due to the effects of the TIA. Another complication is differential diagnosis: other conditions, such as certain types of migraines, electrolyte abnormalities, or intoxication, can cause symptoms that closely mimic those of a TIA. Thus, TIAs can be most effectively detected immediately after the onset of a TIA episode, with transient TIA symptoms being th...

Abstract

In a transient ischemic attack (TIA) alerting device, a motion sensor (24) is configured to attach to or be worn by a subject. A wearable electronic data processing device (10) includes a speaker (14), a microphone (16), a radio transmitter (26), and an electronic processor (40). The processor is programmed to perform a TIA alerting method including: detecting a TIA-symptomatic gait type by processing subject motion data acquired by the motion sensor; responsive to detecting the TIA-symptomatic gait type, executing a TIA assessment questionnaire (70) by outputting questions using the speaker and receiving spoken responses using the microphone; determining a TIA assessment based at least on the spoken responses to the questions of the TIA assessment questionnaire; and conditional on the TIAassessment indicating a possible TIA, outputting a TIA alert radio signal using the radio transmitter.

Description

technical field [0001] The following generally relates to the field of patient monitoring, the field of cardiovascular disease prevention, the field of cardiovascular disease diagnosis, the field of patient health, and related fields. Background technique [0002] A transient ischemic attack (TIA) is an episode of impaired brain function due to loss of blood flow to the brain or key neural regions. Sometimes called "mini-strokes," TIAs differ from strokes in that TIAs usually do not produce lasting neurological damage or extensive tissue death. Symptoms of a TIA episode usually last a few minutes and rarely last longer than 24 hours. However, a TIA is however a serious event because a TIA episode imposes problems with blood flow to the affected brain or nerve tissue. TIA episodes are recognized risk factors for stroke or vascular dementia, and TIA episodes are also often observed in conjunction with non-vascular dementia types such as Alzheimer's disease. Early detection ...
