A phantom picture for the hand in schizophrenia.



This TOP 10 is composed from a list of 37 hand signs for Schizophrenia, and the hand signs are ranked by Log Odds Ratio – which are calculated from the prevalence (%) among Schizophrenics & controls.

1 – Excessive accessory creases [Log Odds Ratio = +3.40]
2 – Pinky: imobility (ankylosis)  [Log Odds Ratio = +3.02]
3 – Lack of expression / rigid expression [Log Odds Ratio = +2.77]
4 – Nail fold plexus visibility [Log Odds Ratio = +2.74]
5 – Sydney line [Log Odds Ratio = +2.45]
6 – Nails: small & underdeveloped (rudimentary) [Log Odds Ratio = +2.43]
7 – Chaotic arrangement of secundary creases [Log Odds Ratio = +2.32]
8 – Simian crease [Log Odds Ratio = +2.27]
9 – Atypical handedness [Log Odds Ratio = +1.80]
10 – Nails: excessively curved outwards (hyperconcex nails) [Log Odds Ratio = +1.74]

It is interesting to notice here that 4 of the 10 hand signs relate to the fingertips (see hand signs 1, 4, 6 and 10). And additionally 4 of the 10 hand signs relate to the hand lines.

And it is fascinating to notice that these TOP 10 hand signs significant for Schizophrenia is a mix of hand features that relate to both the palm (5 hand signs) and fingers (6 hand signs) – hand sign one relates to both the palm and the fingers.

And these 10 hand signs also relate to five of the seven perspectives described by Multi-Perspective Palm Reading, including: the primary, secundary- & accessory lines (4 hand signs), fingernails & nailfold (3 hand sign), hand motorics (2 hand sign), and morphology (1 hand sign).

with 2 comments

A pair of hands of a person who has Down syndrome.



This TOP 10 is composed from a list of 27 hand signs for Down syndrome, and the hand signs are ranked by Log Odds Ratio – which are  calculated from the prevalence (%) among Down syndrome patients & controls.

1 – Single crease on pinky finger [Log Odds Ratio = +4.87]
2 – Ridge line A ends above heart line [Log Odds Ratio = +4.07]
3 – AtD angle is 57 degrees or higher [Log Odds Ratio = +3.96]
4 – Hyperflexible finger joints [Log Odds Ratio = +3.58]
5 – Multiple palmar zones: ridge dissociation [Log Odds Ratio = +3.18]
6 – Large ulnar loops on hypothenar [Log Odds Ratio = +3.02]
7 – Simian crease [Log Odds Ratio = +2.69]
9 – Brachydactly [Log Odds Ratio = +2.50]
8 – Fingerprint: radial loop on ring finger [Log Odds Ratio = +2.46]
10 – Three or more triradii on the hypothenar [Log Odds Ratio = +2.32]

It is interesting to notice here that 4 of the 10 hand signs relate to the palmar hypothenar (‘mount of Moon’ in the fields of palmistry), and additionally the majority of these hand signs relate to the ulnar side of the hand (hypothenar + the pinky and ring finger).

And it is fascinating to notice that these TOP 10 hand signs significant for Down syndrome is a mix of hand features that relate to both the palm (6 hand signs) and fingers (4 hand signs).

And these 10 hand signs also relate to five of the seven perspectives described by Multi-Perspective Palm Reading, including: the dermatoglyphics (5 hand signs), palmar lines & interphalangeal creases (2 hand signs), finger morphology (1 hand sign), motorics (1 hand sign), and skin quality (1 hand sign).

The Sydney Line & the Simian Crease are like ‘Fraternal Twins’!

leave a comment »

Normal palm creases - simian crease - Sydney line.

 Many people are fimiliar with the concept of a simian crease, but there is a likewise fascinating line that has a likewise significance: the Sydney line. In modern medical science both the simian crease & the Sydney line became known as a ‘minor physical anomaly’!

In a 1967 Belgian study Vrydagh-Laoureux pointed out that next to the well-known simian crease (or ‘simian line’ – which became well-known for it’s significance in Down syndrome), there is actually another hand line variant that is associated with related to Down’s syndrome. In the Belgian study this line was described as an ‘extended proximal palmar crease’.

NOTICE: In the traditional palmistry vocabulary this line is often described as: an ‘extended’ or very long head line.

Interestingly, only one year later Australian researchers (Purvis-Smith & Menser, 1968) found that this fascinating palmar line is also frequently found in the hands of patients with congenital rubella – and from that point this ‘fraternal twins line’ of the simian crease has been named: the Sydney line (or sometimes named: ‘Sydney crease’). This twin-analogy could become valuable because many people often find it difficult to discriminate a simian line from a Sydney line!

Example of the Sydney line presented by Purvis-Smith (1972).

Purvis-Smith defined the Sydney line as follows:

“A sydney line occurs where the proximal transverse crease extends beyond the midline axis of the fifth finger towards the ulnar border of the palm the ulnar border of the palm.” (Purvis-Smith, 1972) 


At the end of 20 century a new trend became appearant within the medical scientific community. Researchers began study so-called ‘minor physical anomalies‘ – which concern typically harmless inborn physical markers (that are typically associated with a specific prenatal period) – that have been associated in various disorders.

And especially in the 21 century this approach became popular among researchers who are studying the etiology of e.g. autism, ADHD, Down syndrome, hypoxia & schizophrenia.


Multi-Perspective Palm Reading demonstrates how the Sydney line & simian crease can be understood as a likewise hand line markers. Because (so far) a wide range of studies indicates that in far most diseases & syndromes where the simian crease has been recognized as a significant body marker… the Sydney line became recognized as a likewise significant body marker.

This pattern is seen e.g. in: diabetes mellitus, Down syndrome, fragile-X syndrome, rheumatoid arthritis, and schizophrenia!

Finally, discussion in the Modern Hand Reading Forum have shown that – despite the fact that a Sydney line and a simian line can never be observed in one hand – for many people it quite hard to discriminate a Sydney line from a simian crease. The picture below presents a few fundamental clues which could become helpful to understand the essential components of both lines.

NOTICE: A ‘common hand’ is featured with a life line [I], a head line [II], and a heart line [III]; and various hand line variations can be summarized with the following formulas [IIx = extended head line; II+III = simian crease]:


Obviously, there is a fundamental difference between the Sydney line and simian crease – therefore it appears more appropriate to describe them as ’fraternal twin lines’ instead of ‘identical twin lines’; because while they have a common nature… their manifestion shape is definitiely not identical.

More details are discussed in the following discussion:

How to classify the palmar lines: the simian line, Sydney line & the Suwon crease!

with 17 comments

The study of the palmar lines [folding creases] traces back to the ancient civilisations of the Chinese and Indians as early as 3,000 years B.C. Historically the palmar lines have been adopted as the most important ‘tool’ of the classic Indian palmist with the purpose for ‘the guidance of humanity’. This explains why in all regions of the world the palmar lines became synonymous with the stigma of fortune telling (advocated by so-called ‘predictive palmistry’) – and subsequently debarring the hand lines from the scientific courts.

However, since the end of the 19th century the hand lines have been adopted by scientific researchers for other purposes, including: anthropological classification, personal identification (though the fingerprints are more well-known for this purpose), and hand lines also have a diagnostic purpose!

The combination of the heart line (distal transverse crease) & head line (proximal transverse crease) could be described as representing the most important aspect of the palm lines. The typical characteristics of these two so-called ‘transverse creases‘ (= heart line + head line) can be described as follows (see also the picture above):

• COMMON LINES: The heart line & the head line typically manifest as 2 unconnected lines, and only in human hands these lines typically do not cross the full palm (in the primate palm there are usually mulitiple horizontal lines which cross the full palm).

• SYDNEY LINE: The Sydney line can be recognized by the presence of an extended head line which crosses the full palm, combined with the presence of a normal heart line (both lines are required not to connect/fuse with eachother). NOTICE: From a scientific point, in medical science the Sydney line has been recognized in medical science as a ‘minor physical anomaly’ (MPA), and it became also known as a typical marker for e.g. the hand in Down syndrome, the hand in fragile-X syndrome, the hand in psoriasis & the hand in Schizophrenia. The name‘Sydney line’ was introduced in 1968 by Australian researcher S.G. Purvis-Smith who reported a high prevalance of Sydney lines in patients with congenital rubella. 

• EXTENDED HEART LINE: The extended heart line can be recognized by the presence of a very long heart line which crosses the full palm, combined with the presence of a normal head line (both lines are required not to connect/fuse with eachother). NOTICE: From a scientific point of view there is not much know about the extended heart line.

• SIMIAN CREASE: The simian crease can be recognized by the presence of a fusion between the head line and the heart line – resulting in the impression that one of both lines is missing. NOTICE: From a scientific point, in medical science the simian line has been recognized as a ‘minor physical anomaly’ (MPA), and it became also known as a typical marker for e.g. many syndromes (including Down syndrome) and many diseases such as the hand diabetes mellitusthe hand in rheumatoid arthritis. The name simian line was introduced in 1877 by French physician Paul Broca who described it as an unusual characteristic for the human hand.

The Suwon crease can be recognized by the presence of two complete head lines (not a splitting head line, nor an interrupted head line), and the upper head line fuses/connects with the heart line. NOTICE: The history of the Suwon crease is still very young: it was first described in 2010 by Korean researchers, who found it only in 0.7% of a large Korean sample of 3.532 male hands (in the 1664 female hands it was never observed).

An advanced definition of various types of palmar creases.


The Korean researchers have presented in 2010 a new detailed method for classifying the various types of palmar lines, which includes some interesting elements which can be applied in Multi-Perspective Palm Reading:

“Definition of major and minor palm creases. Major palm creases are defined as follows. Radial longitudinal crease (I) becomes distinct according to the flexion of carpometacarpal joints of the thumb. Proximal (II) and distal transverse creases (III) become distinct according to the flexion of the metacarpophalangeal joints of the second to fifth fingers. Minor palm creases are defined as palm creases which are narrower than the two times of the epidermal groove width in palmprints (1), apart from major palm creases (2), crossing major palm creases (3), or leading to major palm creases by the sharpened end (4).”

SIMIAN LINE – Can the lines in the palm or your hand predict your health or your future?

with 8 comments

The simian line became known as the most well known ‘uncommon’ palmar line variant, and when it is present in a hand it appears as if one of the normal lines is missing. The simian lines is the result of a fusion between the two major ‘palmar transverse creases’: in the fields of palmistry these are also known as the ‘head line’ (in medical science: distal transverse crease) and the ‘heart line’ (in medical science: proximal transverse crease).  About 3% of Western populations have a simian line in one of both hands, however in populations from Asia this percentage may be up to above 10%.

The word ‘simian line’ has a connotation with the hands of primates (simians), which are often featured with multiple likewise horizontal creases that cross the full palm.

And for this reason people often prefer to use other words to refer to the simian line. The most common simian line synonyms in daily language are: simian crease, simian fold, ape crease or the four finger line. In the scientific literature the simian line is usually named as: single palmar transverse crease or four finger line. 


The simian line is most well-known for it’s significance in Down’s syndrome (40%). However, the truth is that the medical disorders associated with simian line are not only seen in the most common chromosomal disorders including e.g.: fragile-X syndrome (18%), Klinefelter syndrome (12%), Turner syndrome (27%) & Marfan syndrome). But the simian line is also more often seen in the most common medical disorders, such as: diabetes mellitus (10%), psoriasis (12%) & rheumatoid arthritis (18%).


Understanding the nature of palmar creases requires a consideration of the palmar dermatoglyphics as well, which concern the fine ridges & grooves in the skin that can be seen in the  palm or your hand with the bare eye (assuming that you have normal eyesight). Because both the palmar creases & the dermatoglyphics largely develop in the 2nd and 3th month of pregnancy under the influences of growth stress forces in the volar skin.

Dermatoglyphics: AtD-angles in trisomy syndromes (trisomy 21 = Down syndrome).

Few people are aware… that the ‘troublesome’ character of the simian line depends significantly on the dermatoglyphics in the so-called mount of Moon (in medical science: hypothenar). For, the high prevalence of the simian line in diseases & syndromes is typically featured with multiple deltas (triradii) and often a high positioned axial triradius, which results in a high AtD-angle. See the figure on the right: all listed trisomy syndromes are also known for a very high prevalance of the simian crease. Therefor, in order to understand the nature of a simian line in the hand(s) of an individual – an analysis of other hand features is a first requirement: the simian line on it’s own means … nothing!


Scientific research R.S. Bali has presented in his book ‘Anthropology of Crease Morphogenesis‘ a summary of studies which have presented significant results for the simian line in the perspective of criminal behavior, character & temperament. But even quite a few celebrities have a simian line!

The Simian Line (2000)


Can the lines in the palm or your hand predict your health or your future? The impact of the simian line is not only significant in the fields of palm reading & scientific research. For sure, the simian line has for touched the lives of  many individuals, and this has even resulted in a movie titled: ‘ The Simian Line‘ (2000). A short synopsis:

“An eccentric palm reader predicts that one of the couples attending an intimate dinner party will end their relationship before the year is over, sparking confusion and doubt amongst the guests, in the tender romantic comedy SIMIAN LINE. The star studded cast includes Harry Connick Jr., Cindy Crawford, Tyne Daly, William Hurt, Monica Keena, Dylan Bruno, Samantha Mathis, Lynn Redgrave, Jamey Sheridan and Eric Stoltz.”

The palmar lines

Despite the fact that the hand lines (creases) have been on the scientific anvil during the past centrury, most people still associate these mysterious wrinkles with gypsies & the stigma of fortune-telling.

While the biological function of the hand lines is not understood well, various branches of academic science have adopted the hand lines as a scientific tool for exploring the genetic- & biological differences between various populations around the world… and the causes of disease!

Many people assume that hand lines are only relevant to the ‘superstitious’ palmist. However, the truth is that antropologists have studied the anatomical aspects of the palmar- & plantar creases in both human- and primate populations. Paul Broca (1877) was the first to stir up interest among anthropologists in the so-called ‘simian crease’ by introducing the ethnic element in the study of creases. And even in 2nd decade of the 21th century few people appear to be aware of the racial differences in the perspective of the hand lines.

The medical significance of the hand lines became appearant after Langdon-Down (1909) described the significance of the ‘simian crease’ for Down syndrome. But his observation was valued with scepsis for quite a while, until the genetic cause of Down syndrome (trisomy 21) was recognized after the discovery of the Karyotype techniques in the 1950.

Later other hand line variations – such as the ‘Sydney line’ and the ‘hockey-stick crease’ – became as well associated with other syndromes, diseases & behavior characteristics – including criminal behavior, autism, schizophrenia, etc.


The following book is solely devoted to the scientific study of the hand lines, including the consideration of various elements that can be described as ‘building stones’ in Mult-Perspective Palm Reading):

Anthropology of Crease Morphogenesis (1991), author: R.S. Bali

Bali writes in the final chapter ‘Creases – Their Scope and Goals’ (page 361):

“… Pronouncements on the association of creases with character and temperament are bound to remain questionable. But future researches on crease features, such as crease surface area, crease splits, crease length, and crease borders, may perhaps throw some light on the relationship. The crease surface area, in term of centimetre counts, cell counts and ridge counts, makes a sufficiently sensitive scale for marking change under differential, physiological, psychological or social stresses. This interesting area of investigation remains to be explored by future researchers.”
