1Consultant Psychiatrist and Clinical Senior Lecturer, University of Western Australia, Perth, WA, Australia.
Summary
Early diagnosis of dementia with Lewy bodies (DLB) is crucial for effective psychiatric management. This case highlights diagnostic challenges and treatment limitations in Australia.
Area of Science:
- Neuroscience
- Psychiatry
- Gerontology
Background:
- Dementia with Lewy bodies (DLB) presents diagnostic challenges due to atypical symptoms.
- Early and accurate diagnosis is essential for timely psychiatric intervention and management.
Observation:
- A case study illustrates delayed DLB diagnosis caused by an atypical clinical presentation.
- The patient did not exhibit typical memory deficits or parkinsonian signs.
Findings:
- Diagnosing DLB can be difficult without classic memory or motor symptoms.
- Limited availability of specific diagnostic investigations and treatments in Australia complicates patient care.
Implications:
- Highlights the need for increased awareness and improved diagnostic criteria for DLB.
- Underscores the importance of accessible specialized investigations and treatments for DLB patients in Australia.

In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

This lesson delves into Lewis acids and bases in the context of the octet rule for electron-deficient compounds. Here, the concept is discussed, emphasizing the group 13 elements like boron or aluminium. Since group 13 elements possess three valence electrons, they form trivalent compounds with a sextet of electrons and a vacant orbital for the central atom. Consequently, these electron-deficient compounds accept electrons from other species to complete their octet in a chemical reaction. They...

Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a model called the Lewis model that simplified the depiction of chemical bond formation and provided straightforward explanations for the chemical bonds seen in most common compounds.

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.

Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual attraction of atoms for a “shared” pair of electrons.
