..... some preventive measures might be applied. In some instances the removal of affected leaves, and perhaps the cutting away of infected wood or stem.
Going back to the forum post. It can clearly be seen that the whole plant is a victim. Look at the leaves. No way can these leaves be rejuvinated. One might go as far as saying, These leaves are symbols of living death. ......
There seems to be a confusion of the issue here ... we're not talking about infection ... we're talking about a nutritional imbalance.
"...These leaves are symbols of living death. ......" a ridiculous oxymoron ... they're not symbolic of anything ... they're a symptom of ill-health. Very different.
The affected leaves may not be 'cureable' but if the nutritional imbalance is corrected in time future growth can be healthy.
This is not the same as 'feeding a sick plant' which is sometimes likened to giving a sick patient a rich meal ... it's more like making sure the patient has the correct nutrition for his bodily functions to operate healthily.

Well said Dove ; a treated chemical imbalance this year should righten the plant for next year . It will probably be a blessing when the leaves eventually fall .
Incidentally , (with the greatest respect) , for someone 'scientifically -qualified' , the spelling and grammatical errors are amazing . Also , I have been cultivating plants in nurseries and at home for over forty-years , and gained experience through trial and error , not through an examination board . My specialities years ago were South-American cacti and S.African caudiciform succulents , containing genera most people have never heard of .
Garden-wise I have a wide spectrum of common & unusual trees , shrubs and perennials , and have come across many problems over the years , most of which were rectified positively !
... For the benefit of all growers. As soon as a plant produces top growth of four to six leaves, check the PH of the soil, if a nitrogen lack is here, try a sprnkling of sulphate of amonia around the plant. I est my case.
For the benefit of those who are not 'scientifically qualified' a PH test will not reveal a lack of nitrogen ... you need kit specific to nitrogen testing (also for potassium, potash etc) ... there are kits and equipment at a wide range of prices, from the cheap and cheerful on Amazon to equipment for the professional costing hundreds of pounds .
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Thanks for your suggestion, I've drenched it with a Sequestrene plant tonic and will let you know how it gets on.
As it's a deciduous plant, I hope that the improvement in the pot can only help, it will drop its leaves and be a better healthier looking wisteria next season.

Sequestrene is a plant tonic (remedies imbalances) , not a plant food .

Next growing season treat again and then maintain a regular feeding regimen (MiracleGro contains beneficial trace elements )
Now go back to sleep !!
