Summary
Noise-making in late-stage Alzheimer's disease can be responsive to interaction and is often perceived as meaningful by others. Treating these vocalizations as meaningful influences their impact on communication for all involved.
Area of Science:
- Gerontology
- Linguistics
- Neuroscience
Background:
- Late-stage Alzheimer's disease (AD) often involves vocalizations like screaming.
- These sounds are frequently disruptive and their meaning is unclear.
- Understanding the communicative function of these vocalizations is crucial.
Purpose of the Study:
- To determine if noise-making in Alzheimer's disease is responsive to conversational interaction.
- To investigate whether co-participants perceive these vocalizations as meaningful or meaningless.
- To explore the consequences of treating these sounds as meaningful.
Main Methods:
- Analysis of selective examples of interaction involving individuals with late-stage Alzheimer's disease.
- Observational study focusing on vocalizations and co-participant responses.
- Qualitative analysis of conversational dynamics.
Main Results:
- Noise-making demonstrates responsiveness to ongoing interaction to some extent.
- Co-participants generally treat these vocalizations as meaningful.
- The interactional treatment of vocalizations influences their consequential meaning.
Conclusions:
- Vocalizations in late-stage Alzheimer's disease can be integrated into conversational interaction.
- Perception and treatment of vocalizations as meaningful can shape their communicative impact.
- This suggests a potential for enhancing communication and connection through interactional adjustments.

01:30Dementia
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.

01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:29Non-Verbal Cues
Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...
01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
01:30Negative and Cognitive Symptoms of Schizophrenia
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

01:26Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...
