When a person is hit in the head, the brain bounces back and forth in the skull, the researchers explain, which can lead to damaged brain cells and even damage to surrounding tissue. Such an impact can break nerve fibers called axons or connective cell tissue called synapses.
What causes obsessive thoughts?

Is it possible to grow new brain cells?
Growing new brain cells—or neurogenesis–is possible for adults. … The good news is that scientists have now discovered that you can grow new brain cells throughout your entire life. The process is called neurogenesis. Specifically, new brain cells–which are called neurons–grow in the hippocampus.
