Research and Epidemiological Challenges

• Difficulty pinpointing specific causes due to multifactorial nature.
• Need for extensive data and collaboration globally.
• The "Birth Cohort Effect" observed starting with individuals born in 1950.

Current Research and Beliefs

• No definitive cause known yet; environmental exposure suspected.
• Large epidemiological studies underway.
• Genetic and microbiome research ongoing.

Prevention and Early Detection Strategies
