Early Signs of Lewy Body Dementia

Brian Callahan • May 16, 2024

Early Signs of Lewy Body Dementia


Mayo Clinic explains "Lewy body dementia is the second most common type of dementia after Alzheimer's disease. Protein deposits called Lewy bodies develop in nerve cells in the brain. The protein deposits affect brain regions involved in thinking, memory and movement. This condition is also known as dementia with Lewy bodies. Lewy body dementia causes a decline in mental abilities that gradually gets worse over time. People with Lewy body dementia might see things that aren't there. This is known as visual hallucinations. They also may have changes in alertness and attention. People with Lewy body dementia might experience Parkinson's disease symptoms. These symptoms may include rigid muscles, slow movement, trouble walking and tremors."

What is Lewy Body Dementia?

Lewy Body Dementia (LBD) is a progressive and complex neurodegenerative disorder characterized by the abnormal accumulation of alpha-synuclein protein deposits, known as Lewy bodies, within the brain's neurons. These Lewy bodies primarily affect areas of the brain responsible for cognitive functions, motor control, and autonomic nervous system regulation. This disorder is marked by a range of symptoms, including cognitive decline similar to Alzheimer's disease, movement difficulties akin to Parkinson's disease, and severe fluctuations in alertness and attention. Patients often experience visual hallucinations, REM sleep behavior disorder (where they physically act out dreams), and severe sensitivity to medications commonly used to treat hallucinations and agitation. The interplay of these diverse symptoms makes LBD particularly challenging to diagnose and manage. The presence of Lewy bodies disrupts communication between brain cells, leading to the gradual deterioration of mental and physical abilities. Understanding and identifying the early signs of LBD can significantly impact the quality of care and management strategies, offering patients and their families a better understanding of the disease and its progression.


Early Signs of Lewy Body Dementia

While the symptoms of Lewy Body Dementia can vary from person to person, several early signs may indicate the presence of the condition. It's essential to recognize these signs and seek medical evaluation for proper diagnosis and management. Some common early indicators of LBD include:


  1. Fluctuating Cognitive Function: Individuals with LBD may experience fluctuations in cognitive abilities, such as memory, attention, and executive function. These fluctuations can manifest as periods of clarity followed by confusion or disorientation. Loved ones may notice that the person's cognitive abilities vary throughout the day or from one day to the next.
  2. Visual Hallucinations: Visual hallucinations are a hallmark symptom of Lewy Body Dementia, often occurring early in the disease course. These hallucinations may involve seeing people, animals, or objects that are not present. Individuals with LBD may also experience illusions, where they misinterpret real objects or people as something else.
  3. Parkinsonism Symptoms: LBD shares several motor symptoms with Parkinson's disease, including bradykinesia (slowed movement), rigidity, and tremors. These Parkinsonism symptoms may appear early in the course of LBD and can affect mobility and balance.
  4. REM Sleep Behavior Disorder (RBD): Many individuals with Lewy Body Dementia experience REM sleep behavior disorder, characterized by vivid, often violent dreams and acting out during sleep. This condition may precede other LBD symptoms by several years and can be a significant early indicator of the disease.
  5. Orthostatic Hypotension: Orthostatic hypotension, or a sudden drop in blood pressure when standing up, is common in individuals with LBD. This symptom may cause dizziness, lightheadedness, or fainting spells, especially when transitioning from lying down to standing up.
  6. Sensitivity to Neuroleptic Medications: Individuals with LBD may have an increased sensitivity to certain medications, particularly neuroleptics or antipsychotic drugs. These medications can worsen LBD symptoms and may lead to severe adverse reactions, including confusion, delirium, and motor impairment.


Recognizing the early signs of Lewy Body Dementia is essential for timely intervention and appropriate care. While LBD poses unique challenges, early detection and management can help improve quality of life and maintain independence for individuals living with the condition.

Does Medicare Cover Home Care for Dementia Patients?

By Brian Callahan 7 Day Home Care • April 30, 2025
Most families are surprised to learn that Medicare provides little to no coverage for non-medical home care services, especially when it comes to help with Activities of Daily Living (ADLs) such as bathing, dressing, grooming, toileting, and meal preparation. These essential services, which help seniors with dementia remain safe and comfortable at home, are typically considered “custodial care” and are not covered by Medicare. As a result, non-medical dementia care is generally a private pay experience. That’s where 7 Day Home Care comes in. As an award-winning and leading private pay home care agency in New York, we specialize in compassionate, highly personalized support for dementia patients—delivered by certified, experienced caregivers trusted by families across Manhattan, Queens, Brooklyn, and Long Island. 7 Day Home Care provides part time to 24/7 in-home care services in Manhattan , Queens , Brooklyn , and Long Island, New York.

Is It Illegal to Leave a Dementia Patient Alone?

By Brian Callahan 7 Day Home Care • April 28, 2025
At 7 Day Home Care, one of the most serious concerns families bring to us is this: Is it illegal to leave a dementia patient alone? Beyond the immediate danger to the individual — including wandering, falls, and medical crises — leaving a person with dementia unsupervised can also pose significant risks to others in the community. Accidental fires, traffic incidents, and public safety emergencies are real possibilities when cognitive impairment goes unmanaged. Across New York City, Long Island, and surrounding areas, elder neglect laws hold caregivers legally responsible for protecting vulnerable adults. But beyond the legal risks, there is a deeper ethical obligation: ensuring the dignity, safety, and well-being of both our loved ones and the communities we live in. In this article, 7 Day Home Care explores the  legal, ethical, and safety implications — and how we can help you protect what matters most. 7 Day Home Care is New York's leading private pay home care agency, providing 24/7 home care services in Manhattan , Queens , Brooklyn , and Long Island, New York.

Standby assistance for seniors is critical for fall prevention

What Is Standby Assistance in Home Care? A Guide for Families

By Brian Callahan 7 Day Home Care • April 14, 2025
What is Standby Assistance in Home Care? A Guide for Families At 7 Day Home Care, we believe that standby home care offers an invaluable service for seniors and their families—one that balances safety, dignity, and independence. By having a trained caregiver present to supervise and intervene only when necessary, we help manage fall risk before it turns into a crisis, preserving mobility and confidence in the home. This proactive approach not only provides families with peace of mind, but also helps seniors avoid the dangerous spiral of a fall leading to hospitalization, followed by rehabilitation, exposure to infections, and potentially accelerated cognitive decline. With standby care, clients are empowered to maintain their daily routines while staying protected—an essential middle ground between total independence and full-time hands-on assistance. It’s thoughtful, preventative care that supports aging in place with strength, stability, and grace.  Rise describes standby assistance as follows: "we all use some form of insurance, but not many of us know what it is to BE insurance. To provide stand-by assist is to be there, just in case someone needs you to help prevent a fall or injury. Stand-by assistance is for clients who can physically function on their own, but may not be safe without someone around to help in case of an emergency. Also, besides safeguarding the client against fall or injury, a stand-by assistant may set up needed equipment or supplies for the client ahead of time, while not participating in the activity. A person who provides stand-by assistance is a literal support person. The 17th-century poet Milton, in Paradise Lost, said it best: “They also serve who only stand and wait.” Stand-by assistants, by their very presence, provide a sense of added safety, security, and calm to clients. Clients know they are not alone, and if something bad happens, someone who knows what to do is right there." 7 Day Home Care provides standby home care services to manage fall risk in Manhattan , Queens , Brooklyn , and Long Island, New York.

How In-Home Care Reduces Fall Risk for Seniors at Home

By Brian Callahan 7 Day Home Care • April 9, 2025
How In-Home Care Reduces Fall Risk for Seniors at Home Falls are one of the most serious health risks facing older adults at home, often leading to a cascade of complications that extend far beyond the initial injury. A single fall can result in fractures, head trauma, or internal injuries—many of which require hospitalization and lengthy stays in skilled nursing facilities or rehabilitation centers. These disruptions can severely impact a senior’s independence, mobility, and mental health, sometimes triggering a decline in overall well-being that is difficult to reverse. According to American Academy of Family Physicians , The American Geriatrics Society and British Geriatrics Society recommend that all adults older than 65 years be screened annually for a history of falls or balance impairment. In addition to the physical toll, fall-related injuries frequently lead to increased reliance on long-term care, elevated stress for family caregivers, and significant financial burden. Preventing falls is not just about safety—it’s about protecting a senior’s health, dignity, and quality of life. A fall in an elderly person can trigger a cascading effect , leading to a decline in physical and cognitive function, increased fear of falling, social isolation, and reduced quality of life, potentially leading to further falls and injuries. 7 Day Home Care is your top home care agency in Manhattan, Queens, Brooklyn, Nassau County, and Suffolk County, New York. Please call us today at 516-408-0034 to learn more about fall prevention strategies, and explore the prospects for home care services for your loved one.

7 Tips for Alzheimer’s and Dementia Care at Home: A Family Guide

By Brian Callahan 7 Day Home Care • April 3, 2025
7 Tips for Alzheimer's and Dementia Care at Home: A Family Guide Caring for someone with Alzheimer’s diseas e, dementia, or any form of cognitive impairment at home is among the most demanding forms of caregiving due to the condition’s progressive nature, emotional complexity, and the constant need for vigilance. Unlike other medical conditions that may have clear treatment paths or predictable routines, cognitive decline affects every aspect of a person’s identity—memory, communication, behavior, and judgment—often changing day to day. At 7 Day Home Care, we understand that this kind of care requires not only physical assistance but also deep emotional patience, consistency, and specialized skills to manage wandering, sundowning, confusion, and challenging behaviors, all while preserving the person’s dignity and autonomy. The emotional toll on family caregivers can be immense, especially when a loved one no longer recognizes them or becomes increasingly withdrawn or aggressive. Our highly trained caregivers are equipped to meet these challenges with empathy and expertise, offering families the support they need to navigate one of life’s most complex caregiving journeys. 7 Day Home Care provides best home care agency services near you in Manhattan , Queens , Brooklyn , Nassau County, and Suffolk County, New York.
