Synaptic problems are a big reason why people's thinking skills get worse in diseases that harm the brain, like Alzheimer's. Our brain learns and remembers things mainly through synapses, which are the connections between brain cells, or neurons. When these connections don't work properly, it can make things like memory, focus, and reasoning much harder.
Bad Protein Folding: In diseases like Alzheimer's, certain proteins, like amyloid-beta and tau, don’t fold the way they should. They build up and disrupt how synapses work, which can lead to more inflammation in the brain and damage to brain cells.
Failed Signal Sending: Neurotransmitters are vital for sending messages between synapses. In diseases like Parkinson’s, the neurons that produce dopamine start to break down. This messes up communication and can hurt both movement and thinking skills.
Cell Damage from Stress: Too much of certain harmful particles can hurt neurons and their synapses, making thinking harder. For example, this kind of damage happens in Huntington’s disease.
In Alzheimer's disease, when synapses are lost, people experience worse memory. Research shows that when there's a 40% loss of synapses, it can lead to a big drop in memory ability. On the other hand, finding ways to improve synapse function could help promote learning, even for older brains or those affected by neurodegenerative diseases.
When we understand these problems at the cell level, we can better address the issues that lead to cognitive decline. Taking care of our synapses is very important for keeping our thinking skills sharp.
