Definition: When does intercellular communication become disrupted in age-related neurodegenerative diseases?

Intercellular communication refers to the exchange of signals between different cells in the body. In the context of the brain, this communication is essential for coordinating various processes such as neuronal signaling, synaptic plasticity, and overall brain function. However, in age-related neurodegenerative diseases, this communication becomes disrupted, leading to impaired neuronal function and ultimately contributing to disease progression.

The exact timing of when intercellular communication becomes disrupted in age-related neurodegenerative diseases can vary depending on the specific disease. However, it is generally believed that this disruption occurs early in the disease process, even before the onset of clinical symptoms. This early disruption can be attributed to various factors, including the accumulation of abnormal proteins, oxidative stress, inflammation, and mitochondrial dysfunction.

As the disease progresses, the disruption of intercellular communication becomes more pronounced. This can manifest as impaired neurotransmitter release, altered synaptic transmission, and impaired neuronal connectivity. These disruptions contribute to the characteristic symptoms of age-related neurodegenerative diseases, such as memory loss, motor dysfunction, and cognitive decline.

Understanding the mechanisms underlying the disruption of intercellular communication in age-related neurodegenerative diseases is crucial for developing effective therapeutic strategies. By targeting these mechanisms, researchers hope to restore normal communication between cells and potentially slow down or even halt the progression of these devastating diseases.
