Can brain lesions heal or disappear? |
1. Some of the fresh spots are filled with water (swellling and inflammation, somewhat like after a bee sting). These glow on MRI. The swelling, and some of the immune cells, causing this go away over weeks to months.
2. If there is demyelination and death of neurons a "black hole" appears. Even these can go away.
Two reasons for improvement. less inflammation means fewer spots (we saw this in the first betaseron trial) and repair (some myelin regrows) |
