Tuberous sclerosis complex (TSC) is highly variable in clinical presentation and findings. Disease manifestations continue to develop over the lifetime of an affected individual. Accurate diagnosis is fundamental to implementation of appropriate medical surveillance and treatment. Continue reading
The 2017 McDonald criteria continue to apply primarily to patients experiencing a typical clinically isolated syndrome, define what is needed to fulfil dissemination in time and space of lesions in the CNS, and stress the need for no better explanation for the presentation. Continue reading
The Expanded Disability Status Scale (EDSS), an accepted method of quantifying disability in Multiple Sclerosis (MS) consists of an eight-function system scale monitoring motor, sensory, cerebellar, brain stem, visual, bowel and bladder, pyramidal and other functions.
The diagnostic criteria for tuberous sclerosis complex (TSC) were revised at the Tuberous Sclerosis Complex Consensus Conference, July 1998.
Definite TSC: Two major features or one major feature plus two minor features
Probable TSC: One major feature plus one minor feature
Possible TSC: One major feature or two or more minor features
What Is An Attack?
- Neurological disturbance of kind seen in MS
- Subjective report or objective observation
- 24 hours duration, minimum
- Excludes pseudoattacks, single paroxysmal episodes Continue reading
1980 Criteria for the Classification of Systemic Sclerosis
The American College of Rheumatology (former American Rheumatism Association – ARA) has defined criteria, that are 97 % sensitive and 98 % specific for systemic sclerosis (SSc) as follows:
Proximal diffuse (truncal) sclerosis (skin tightness, thickening, non-pitting induration)
The diagnosis of Amyotrophic Lateral Sclerosis (ALS) requires
A. the presence of:
(A:1) evidence of lower motor neuron (LMN) degeneration by clinical, electrophysiological or neuropathologic examination,
(A:2) evidence of upper motor neuron (UMN) degeneration by clinical examination, and
(A:3) progressive spread of symptoms or signs within a region or to other regions, as determined by history or examination, together with
