Insights
Evidence suggests a link between vascular disease and mania. Further research is needed to confirm if vascular mania is a distinct subtype, potentially with late-onset characteristics.
Area of Science:
- Neurology
- Psychiatry
- Vascular Medicine
Background:
- The relationship between vascular disease and mania is not well-defined.
- Existing literature includes case reports and varied terminology, hindering clear understanding.
Purpose of the Study:
- To review evidence associating vascular disease with mania.
- To evaluate proposed diagnostic criteria for this association.
Main Methods:
- Literature search of MEDLINE, PsychInfo, and EMBASE (1996-2006).
- Review of articles due to limited data, precluding systematic evidence level application.
Main Results:
- A tentative association exists between mania and vascular risk factors/cerebrovascular disease.
- The term "vascular mania" is proposed for clinical utility, despite implying causality.
- Proposed criteria for late-onset mania (age 50+) show non-specific neuroimaging and neuropsychological changes.
Conclusions:
- Further studies are required to establish vascular mania as a distinct subtype with late-onset features.
- An alternative framework for conceptualizing vascular mania is presented.
Objective:
To review the evidence for an association between vascular disease and mania, and in this context, to assess the suitability of previously proposed diagnostic criteria.
Method:
Relevant articles were retrieved and reviewed with the aid of search engines [MEDLINE, PsychInfo and EMBASE from 1996 to 2006] using pertinent search terms. Because of the paucity of data, systematic criteria for levels of evidence could not be applied.
Results:
The literature is limited by the preponderance of case reports or case series, the use of overlapping terms, such as secondary mania, disinhibition syndrome and poststroke mania, and variable definitions of mania per se. There is general support for a tentative association between mania and vascular risk factors, and also between mania and cerebrovascular disease. Such associations seem best described by the term vascular mania for the sake of clinical utility, although it erroneously conveys causality. Proposed diagnostic criteria have defined a late-age at onset (50 years +) sub-type of mania, with associated neuroimaging and neuropsychological changes which are not specific to this age group.
Conclusion:
Further studies are needed to determine whether mania associated with vascular disease is a specific and separate sub-type with a late-age at onset. An alternative framework for considering vascular mania is proposed.
