Brown patches can be treated; for instance, you can:
Dollar spot is another common lawn disease that creates small, silver-dollar-sizes spots on grass. It is quite common in nitrogen-deficient lawns. To identify dollar spot disease, look for small, straw-colored patches of grass with lesions on individual blades.

In order to treat lead blight, you can:
Melting out is a fungal disease that starts with leaf spots and progresses to thinning grass or bare patches. To identify this disease before it spreads and affects your whole lawn, look for small lesions on grass blades that spread and cause thinning. Dense turf and excessive moisture are two leading causes of melting-out fungal disease.
To deal with lawn melting out, make sure to:
Slime mold is a non-pathogenic organism that forms slimy patches on grass blades but does not kill the grass. To identify slime mold, look for slim, gray, or white patches on grass blades. Typically, it is caused by high humidity or damp weather conditions.
