Dementia with Lewy Bodies (DLB)
Dementia with Lewy Bodies (DLB) is a progressive type of dementia caused by abnormal protein deposits called Lewy bodies building up in brain cells. These deposits affect thinking, movement, behaviour, and sleep.
It is one of the most common types of dementia, but is often misdiagnosed because it shares features with Alzheimer’s and Parkinson’s disease.
🔎 Common Signs Families May Notice
✨ Fluctuating confusion and alertness
Good days and bad days are common. Someone may appear clear and engaged at times, then suddenly very confused or drowsy.
👀 Visual hallucinations
Seeing people, children, or animals that aren’t there is very common and often happens early.
🚶 Movement changes (Parkinson-like symptoms)
Stiffness, slowed movement, shuffling walk, tremors, or balance problems.
🌙 Sleep disturbances
Acting out dreams (talking, shouting, moving in sleep) can be an early warning sign.
💊 Sensitivity to antipsychotic medications
Some medications can cause severe worsening of confusion or mobility, so medical guidance is essential.
🧩 How It Differs From Alzheimer’s
• Memory loss may not be the first symptom.
• Hallucinations and movement symptoms often appear early.
• Symptoms can fluctuate significantly from day to day.
❤️ What Families Should Remember
• These changes are caused by the disease not the person.
• Calm routines, reassurance, and good lighting can help.
• Always inform healthcare professionals about medication reactions.
• You are not alone support is available.
