Summary
Recurrent transient global amnesia (TGA) may precede the development of primary progressive aphasia (PPA). This case series describes three patients with a history of TGA who were later diagnosed with PPA.
Area of Science:
- Neurology
- Neurodegenerative Diseases
- Cognitive Neurology
Background:
- Transient global amnesia (TGA) is a distinct neurological condition characterized by sudden, temporary memory loss.
- Primary progressive aphasia (PPA) is a neurodegenerative disorder affecting language abilities.
Observation:
- This study presents a case series of three patients with a history of recurrent TGA.
- These patients subsequently developed symptoms consistent with PPA.
Findings:
- All three patients experienced recurrent episodes of TGA.
- Diagnoses of PPA were confirmed through speech pathology evaluations, neuropsychometric testing, and neuroimaging.
- Brain imaging revealed distinct patterns of hypometabolism and decreased perfusion in language-associated brain regions.
Implications:
- The findings suggest a potential link between recurrent TGA and the subsequent development of PPA.
- Further research is warranted to explore the underlying mechanisms and clinical significance of this association.
- This observation may inform diagnostic approaches for patients presenting with recurrent TGA and evolving language deficits.

01:13Amnesia
Amnesia is a condition marked by long-term memory loss, which impairs the ability to recall past events or create new memories.
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...

01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
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...
01:26Higher Mental Functions of Brain: Learning and Memory
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or playing an...
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...
01:21Dissociative Amnesia
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...
