Alzheimer's Diagnosis and Machine Learning

What is one of the main challenges in diagnosing Alzheimer's disease early?

• Limited availability of specialists

• Lack of effective treatments

• High cost of diagnostic tests

• Symptoms are often mistaken for normal aging

How do researchers in Japan propose to detect early signs of Alzheimer's?

• Through blood tests

• With genetic testing

• Using brain scans

• By analyzing speech patterns using machine learning

What is the main reason speech is used in Alzheimer's diagnostics?

• Speech is easy to record

• Speech changes are early indicators of cognitive decline

• Speech tests are inexpensive

• Speech is the only symptom of Alzheimer's

What type of data did the researchers collect for their study?

• Audio recordings of speech

• Genetic information

• Brain imaging scans

• Blood samples

What was the role of the AI computer program in the study?

• To diagnose Alzheimer's directly

• To collect audio data by conversing with participants

• To analyze brain scans

• To administer medication

Which algorithm showed promise in identifying Alzheimer's more accurately than TICS?

• Neural Network Model

• Support Vector Machine

• Extreme Gradient Boosting Model

• Linear Regression Model

What is a limitation of the current study mentioned in the video?

• The study did not use any control group

• The algorithms were not tested on real patients

• The sample size was small and not diverse

• The study was conducted only in the United States

What potential benefit does AI offer in diagnosing Alzheimer's according to the video?

• It can eliminate the need for any medical tests

• It can cure Alzheimer's disease

• It can provide a low-cost, accessible diagnostic option

• It can replace doctors entirely

What is a potential future application of this AI technology?
