If your mom is still mobile and active, she might do well in living in the same place that my mom resided at for awhile prior to her stroke. When she was still healthy, she lived off of Pegg Rd in the senior apartments there [Lexington Park Adult Community - 21895 Pegg Rd Lexington Park - 240-725-0111]. She was the first tenant in her 2-bedroom apartment, and it really was quite lovely. The facility had a beautiful common room, an indoor pool, a jacuzzi, library, computer room, etc. She loved living there, and enjoyed being close to shopping, doctors, and friends and family. Had she not had her stroke, she would still be living there, loving every minute of it. The place is designed for people over 55, and all residents were ambulatory, some even having regular jobs and community interests.
When her health declined and she required 24-hour nursing care, she moved in to Solomon's Nursing Center off of Dowell Rd in Solomons. They had a dynamite program where she could meet with various therapists (occupational, speech, physical, etc.) to try to get some kind of recovery of her lost abilities. Because these rooms were in the "medical" side of the house, they were quite sterile. Clean, nice, and well-staffed, but still pretty sterile. On the other hand, Solomon's Nursing Center also has another section dedicated to folks who do not require medical treatment. Those apartments are very lovely, too.
Good luck!
