Yes, high sugar intake may contribute to neurodegenerative diseases like Alzheimer's disease and dementia. High-sugar diets can lead to insulin resistance, which can increase the risk of neurodegeneration. 

Explanation

• Insulin resistance
  High-sugar diets can cause insulin resistance in the brain, which can make it harder for the brain to remove neuronal debris. 
• Type 2 diabetes
  High-sugar diets can promote weight gain and insulin resistance, which can lead to type 2 diabetes (T2D). T2D is a risk factor for Alzheimer's disease. 
• Fructose
  Fructose, a simple sugar, can trigger neural activity that may lead to progressive brain changes. 
• Brain volume and memory
  Studies have shown that higher sugar intake is associated with lower brain volume and episodic memory. 

To reduce the risk of developing neurodegenerative diseases, you can try to limit your sugar intake and eat a balanced diet. You can choose whole foods over processed foods and limit sugary drinks and snacks.
