A tremor in a resting hand is a classic sign, but it’s not the only one. Look for a tremor that persists, especially when relaxed. Another early indicator is bradykinesia, or slowness of movement. Simple tasks like getting dressed or buttoning a shirt may take significantly longer and require more effort. Rigidity, a feeling of tightness or restricted movement, can affect any part of the body, leading to a stooped posture or a shuffling gait. Balance problems and falls are also common, so be observant if your partner seems unsteady or trips more frequently. Changes in speech can be subtle but significant. Speech may become softer, slurred, or monotone.
